xx is the debut studio album by the English indie pop band the xx. It was released on 14 August 2009 by Young Turks, then an imprint label of XL Recordings, and recorded from December 2008 to February 2009 at the label's in-house studio in London. Producing the album, Jamie Smith of the xx created electronic beats for the songs on his laptop and mixed them in a detailed process with the audio engineer Rodaidh McDonald, who attempted to reproduce the intimate, unembellished quality of the band's original demos.

Along with the xx's early R&B influences, the album has drawn comparisons from journalists to alternative rock, electronica and post-punk sounds. Its largely melancholic songs feature minimalist arrangements built around Smith's beats and instrumental parts recorded by the other members of the band, including Oliver Sim's basslines and sparse guitar figures by Baria Qureshi and Romy Madley Croft, who employs reverb in her lead guitar playing. Most of the songs are sung as low-key duets by Croft and Sim, both of whom had written emotional lyrics about love, intimacy, loss and desire.

Released to widespread acclaim, xx was named one of 2009's best records and received praise for the band's atmospheric style of indie rock and pop as well as the interpersonal dimension of the performances. Commercially, it performed steadily over its first few years of release, becoming a sleeper hit in the United Kingdom and the United States, and eventually sold one million copies. Although major media outlets had largely ignored the band at first, and none of its singles became hits, xx received greater exposure from the licensing of its songs to television programmes and the band's Mercury Prize win for the album in 2010.

This album is the only one which released as the four-piece band. Shortly after the album's release, and with differences between Qureshi and the rest of the group leading to her dismissal, the xx continued to play as a trio on a protracted concert tour that helped increase their fanbase, reputation in the press and confidence as performers. xx proved highly influential in subsequent years, as its distinctive stylistic elements were incorporated by many indie bands and top-selling pop acts. One of the most acclaimed records of its era, it has appeared on top album lists published by NME, Rolling Stone and The Guardian.

While students at South London's Elliott School in 2005, childhood friends Romy Madley Croft and Oliver Sim formed the xx with Jamie Smith and Baria Qureshi. Croft and Sim played guitar and bass, respectively, and dueted as the band's vocalists, while Smith programmed electronic beats for their songs and Qureshi doubled as a keyboardist and additional guitarist. During late nights, Croft and Sim either shared lyrics with each other through instant messaging or rehearsed quietly with Smith and Qureshi in their bedrooms so they would not disturb the rest of the household. The xx were greatly influenced by American R&B producers such as The Neptunes and Timbaland, whose minimalist productions incorporated vocal harmonies, clapping percussion, unconventional samples and pronounced beats. The band covered Aaliyah's "Hot Like Fire" (1997), Womack & Womack's "Teardrops" (1988) and other past R&B hits when they performed live and recorded their demos.

After posting the demos on their Myspace page, the xx drew the interest of Young Turks, an imprint label of XL Recordings. They submitted the demos to XL's head office at Ladbroke Grove and were subsequently signed to a recording contract. The group worked with producers such as Diplo and Kwes, to no success before they were introduced to the audio engineer Rodaidh McDonald by the xx's manager Caius Pawson, who gave him three CDs of demos titled "Early Demos", "Recorded in Rehearsal Space" and "What Producers Did Wrong". McDonald was impressed by the intimate quality and use of silence on the demos, which both he and the band felt may have challenged other producers who wanted to incorporate their individual tastes: "They'd worked with about four other producers before then that had – and no discredit to them – I guess they'd seen a lot of space to add a kind of stamp on. There was a lot of empty space in the xx's music, even then, in the 'Early Demos'. But we just found that the best stuff was the most sparse."

At the behest of XL's owner Richard Russell, the xx recorded their debut album at the label's small, in-house recording studio – XL Studio – making them the first act to record there. It was once the head office building's rear garage before Russell transformed it at the beginning of 2008 into a makeshift writing, rehearsal and demo space for XL's artists. McDonald was assigned in September to manage and properly equip the room, which he liked because it was soundproof and "isolated from the rest of the office, so it wasn't like you were working in the record company's presence." Croft, on the other hand, called it a "pretty confined space" the size of a bathroom. Over the next few months, McDonald and Pawson prepared a budget for the label to fund the studio's preliminary setup, which would have recording equipment specifically suited for the xx, including a modestly sized soundboard ideal for recording a small group.

The xx started to record the album in December 2008 with McDonald, who engineered the sessions. They would usually record at night after XL's staff had left, which Croft said made it feel "isolated and quite creepy". To reproduce the sound he had heard on the band's demos, McDonald had them write down their instruments' settings and test different areas of the studio to determine where he should record each member. Sim, who played a Precision Bass manufactured in the 1970s, was often recorded in the hallway outside the studio with a Fender Bassman, one of several amplifiers McDonald experimented with for xx. Some of Qureshi and Croft's guitars were also done in the hallway. Qureshi played a Gibson SG with a Fender Hot Rod Deluxe or Blues Deluxe amplifier, while Croft played an Epiphone Les Paul on most of the album and a Gibson ES-335 on a few songs. For her lead guitar parts, Croft used a delay pedal and a Roland Micro Cube amplifier with a reverb setting, which McDonald felt would best replicate her "icy", echo-filled sound on the demos.

After all the instrumental elements had been tracked, Croft and Sim recorded their vocals together, rarely singing backup to one another on any of the songs. McDonald believed it was important for the singers to be "in sync" and share the same mental state or mood when performing full takes of songs, some of which he said benefited from when they were both "quite tired and emotional". He had Croft and Sim sing into Neumann microphones on most of the songs in order to make their vocals sound as "intimate" and conversational as possible. The microphones were among the more expensive items he borrowed for the studio's preliminary setup so XL would not be overwhelmed with a costly budget.

Despite McDonald's close involvement, the xx had been encouraged to self-produce their album by Russell; he believed it would remain faithful to both the band's distinctive live sound and the DIY ethic practised at XL since its beginnings as a rave label. Smith was chosen by the rest of the group to produce xx. He used Logic 8 recording software on his Mac Pro and often worked late nights in a nearby conference room while they recorded in the studio with drafts of his beats. Smith produced rhythm tracks with an Akai MPC sampler, which he occasionally processed through a Roland RE-201 and other effects units. He also created click tracks for the rest of the band to keep timing when they recorded their individual parts. After those parts had been recorded, he refined and incorporated his beats into the songs for three to four weeks. Croft trusted that Smith, who did not want to conceal any imperfections by overproducing xx, would make it practical for them to perform live rather than layer the songs with several guitar or vocal elements.

Most of xx was recorded from late December 2008 to late January 2009 before McDonald and Smith began an exhaustive mixing process, which lasted two weeks. For each song, they mixed one or two tracks of each instrument and used Waves Audio components to equalise the recordings. Having enjoyed how the demos captured unintended background noises such as street sounds, McDonald deliberately left certain sounds that would have otherwise been unwanted in the final mix. "I wanted it to sound like people in a room, rather than this polished kind of perfect crystalline thing", he explained. "It was all the small details that we really liked."

In February 2009, the group wrote and recorded "Fantasy", "Shelter" and "Infinity" before finishing xx, possibly by month's end according to McDonald; the album's liner notes credited the final date of recording as April. Sim sang his vocals for "Infinity" on the side of the studio opposite from Croft after his microphone had been unintentionally moved there, which resulted in a distant-sounding vocal exchange on the song. While recording "Shelter", a mechanical part from the guitar amplifier loosened and caused it to make a clattering sound, which McDonald and the xx chose to retain. "It was just like this missing piece of percussion that the track needed!", McDonald recalled.

The songs on xx are composed around a framework of basslines and beats, while incorporating simple guitar riffs for melody, rhythm and texture; their melodic notes are separated by rests. Croft said the band's style of instrumentation became defined by the limited equipment they originally used: "My guitar sound pretty much came from discovering there was reverb on my little practice amp and really loving the mood it created." The loudest song, "Intro", is a largely instrumental recording with double-tracked beats, distorted keyboard, non-lexical vocables and a guitar riff. Songs such as "Crystalised" and "VCR" begin with a melodic ostinato and some understated sounds, including a xylophone on the latter, before leading to quietly sung verses. Croft and Sim exchange verses on "Crystalised" while backed by the sound of drum stick clicks and basslines before the beat is heard. On the austerely arranged "Night Time", Croft sings its first two minutes over only guitar and bass before its beat develops. "Fantasy" is highlighted by a shoegazing guitar sound.

While McDonald observes a predominant R&B element, Russell feels the xx's music evokes the early hip hop records he listened to when he was young, as they are often limited to vocals, samples and beats. Music journalists, however, infer from xx that their influences are alternative rock acts such as Portishead, Young Marble Giants and Cocteau Twins, the last of which Croft said she had never heard before the album was released. The Scotsman describes xx as a minimalist, melancholic indie pop record that draws on elements from electronica and R&B, as well as The Cure and other alternative groups. According to Sarah Boden of The Observer, the album's unadorned, dream pop love songs are reminiscent of Cocteau Twins and Mazzy Star, because they feature low tempos, moody melodies and rhythms influenced by R&B and dubstep. Their arrangements have what Neil McCormick calls "a very British, industrial aspect", somewhat similar to the dub-inflected post-punk sound of the English producer Martin Hannett and his work with the band Joy Division. Both Croft and Sim said their combination of seemingly disparate influences could be attributed to the variety in each band member's music collection.

On xx, Croft and Sim touch on themes of love, desire and loss in their songwriting, which Croft said has "always been based around emotions, right from the start. My favourite songs are usually quite sad and I think heartbreak is something that so many people can connect with." Like Croft, Sim said he wrote much of his lyrics at night when his emotions ran "a bit higher". Because of their reserved personalities, Robert Christgau believes they rely on a low-key, vulnerable style and exchange "ideas about intimacy as contemporaries, comrades, prospects, lovers, ex-lovers and friends". According to NME magazine's Emily Mackay, all of the songs deal with the consuming emotions associated with first love, including the tacit intimacy on "VCR", the yearning expressed on "Heart Skipped a Beat" and the premature affection warned of on "Crystalised". Petra Davis from The Quietus argues that the thematic crux of xx is in the succession of songs from "Islands" to "Shelter", each of which sees "a radical shift in perspective on a similar – perhaps a single – love story."

The album's Roman numeral title refers to each of the band members having turned 20 years old by the time xx was released. Because of their age, many critics interpret the songs as nocturnal depictions of adolescent lust. Philip Sherburne writes in Spin that xx brims with a "young lust" often found in rock music, and recordings such as "Fantasy" and "Shelter" express a jaded yearning, particularly in a lyric from the latter song: "Can I make it better with the lights turned on". Croft vehemently denied this: "We were writing these songs when we were 17. I can honestly say I've never thought this is about my sex life." Croft and Sim, who are both gay, did not intend for the songs to be heard as romantic duets; she said they are singing "past each other" rather than to each other. Having combined their individually written lyrics, they could not definitely explain what their songs were about, although Croft said Sim's lyrics resonated with her nonetheless and enjoyed the personal interpretation it offered. "You can put them into your own life", she explained, "like, 'Oh, this is my song.'" The romantic situations Sim wrote of had been inspired by other people. "I hadn't really had any relationships to be working off, but I had a huge interest in life, and looking at other people's relationships around me", he said.

"Crystalised" was released as the xx's debut single on 27 April 2009 and helped build interest in the band among listeners and journalists. It was part of a series of singles from xx, which included "Basic Space" on 3 August, "Islands" on 26 October and "VCR" on 25 January 2010. The band's music was largely ignored by BBC Radio 1 in the United Kingdom, and other major media outlets also believed they did not warrant strong attention; one editor from NME said at the time that the band was not ideal for their magazine's front cover. In the United States, the group benefited from the word-of-mouth marketing of blogs, beginning when they performed six consecutive sold-out shows at New York City clubs such as Pianos and the Mercury Lounge months prior to the album's release.

Several of the songs from xx were licensed by XL to television programmes in the UK and North America. "Intro" became widely used as theme music in television, including sports highlights, episodes of series such as Law & Order and Cold Case, an advertisement for AT&T and BBC's coverage of the 2010 British general election. Along with their placement in television, songs from the record were used by North American chain stores such as Starbucks and Urban Outfitters as background music at their locations. According to McCormick in 2010, these marketing strategies helped the xx develop enough media presence to garner "over half a million sales around the world without ever having anything as vulgar as a hit". Kris Chen, XL's A&R senior vice-president, believed the exposure was desired and necessary for promoting an album that was not "driven by pop radio". Although the band realised their music had to be marketed somehow, Croft expressed reservations about "putting our music on everything, just to put it to anything just for the sake of money".

xx was released by Young Turks in August 2009 to widespread critical acclaim. At Metacritic, which assigns a normalised rating out of 100 to reviews from professional publications, the album received an average score of 87, based on 25 reviews. According to Alexis Petridis, it was the most acclaimed album of the year.

Critics particularly praised the xx's sound on the album; Simon Price wrote in The Independent that they were being universally lauded for their "atmospheric indie rock, and rightly so". The Daily Telegraph's Jack Arnhold regarded xx as "one of this year's most beautiful and original debut albums". Reviewing for The New Yorker, Sasha Frere-Jones remarked that the album rewards repeated listens because of the band's disciplined playing, while Mark Edwards of The Sunday Times said it succeeds with simple but "very near perfect" pop songs. AllMusic's Heather Phares called the instrumentation impeccable and was impressed by how poised and refined such a young group sounds. In The Irish Times, Jim Carroll said the exceptional chemistry behind Croft and Sim's melancholic duets is the highlight of "this drop-dead gorgeous dream-pop symphony". Matthew Cole from Slant Magazine believed their rapport gives an emotional weight to the music, which he said sounds timeless and capable of appealing to both indie and popular tastes. Christgau, writing in MSN Music, was somewhat more impressed by the music than by the lyrics, although he said the underlying force behind the singers' charmingly minimalist songs is a "spiritual dimension" offered by their ability to "shift roles without ever seeming hostile, cold or even unsupportive".

Some reviewers had reservations. Jon Caramanica of The New York Times felt the singers are too disengaged and reticent to reveal any genuine emotion. "Though they're singing to each other, it rarely feels intimate", he wrote, "more like two shy teenagers, eyes cast downward, awkwardly talking to the ground". In the opinion of PopMatters' critic Ben Schumer, the consistent structures and tempos of the songs makes them sound somewhat monotonous on what is an otherwise affecting nocturnal mood piece. Conversely, Joshua Errett from Now found the music and singing mesmerising but lamented the lyrics, which he deemed emotionally immature and "overwrought".

At the end of 2009, xx appeared on several critics' lists of the year's best albums, including rankings of ninth by Rolling Stone, sixth by Uncut, third by Pitchfork, second by NME and fourth by the Chicago Tribune critic Greg Kot. The Guardian named it the year's best record in their annual critics poll and Tim Jonze, the newspaper's editor, hailed it as not only "the sound of 2009, [but also] a distinctive musical statement of the like we may never get to hear again". It also finished seventh in The Village Voice's Pazz & Jop poll of American critics and third in HMV's Poll of Polls, an annual list compiled by the British music retailer HMV and collated from best-album nominations made by journalists in the English and Irish music press. In decade-end lists of the greatest records from the 2000s, The Sunday Times and its sister paper, The Times, ranked xx seventy-seventh and thirtieth, respectively. The record was also included in the 2010 edition of Robert Dimery's music reference book 1001 Albums You Must Hear Before You Die.

xx was not an immediate chart success, but eventually became a sleeper hit. It debuted at number 36 on the UK's Official Albums Chart and sold 4,180 copies in the first week after it was released, while in the United States it did not chart higher than number 92 on the Billboard 200. The album sold steadily for the next 44 weeks until July 2010, when it experienced a sharp increase in sales and a jump from number 44 to 16 on the British chart following its announcement as a nominee for the Mercury Prize, an annual award given to the best album from the UK and Ireland. By then, it had sold more than 150,000 copies in the UK and 179,000 copies in the US. Before the nominations shortlist had been announced, bookmakers and critics considered the xx as favourites to win the award over the more high-profile artists Corinne Bailey Rae, Paul Weller and Dizzee Rascal. The album remained in the top 20 of the UK chart in the weeks leading up to the Mercury Prize ceremony in September. Immediately after its win that week, it climbed from number 16 to 3 on its highest weekly sales – 28,666 copies – and reached a total of 212,835 copies sold. McCormick, one of the critics who predicted its victory, explained that it "seemed the record that most represented Britain" with its charmingly intimate style and unique take on modern pop tastes, while citing its win as "a rare example of the Mercury Prize doing music lovers a service".

By December 2010, xx had sold 325,000 copies in the UK and was certified platinum by the British Phonographic Industry. In the US, the album reached 350,000 copies sold by June 2012 with consistent weekly sales during its first two years of release, which Time magazine's Melissa Locker said was "quite a feat" in an era of music piracy, media streaming and YouTube. Adding to its commercial success, songs from the album were covered by a variety of major recording artists, including Shakira, Gorillaz and Orchestral Manoeuvres in the Dark.

Although xx had been highly anticipated by XL, the album's success exceeded expectations in the press. McDonald said their direction and sound would have been entirely different had expectations been higher, while Croft was "baffled" by the acclaim given to what she viewed as an album they had made "for themselves". Sim had mixed feelings about its success, believing it could affect his songwriting in the future: "This album was done with no expectations. No one knew who we were. When I was writing the songs, I didn't think anyone other than Romy or James would ever actually hear them. Now I know so many people will. I might feel I have to be a bit more private."

At the Mercury Prize ceremony, Sim said the time since the album's release had "felt like a haze", but that the event served as "a moment of clarity". In their acceptance speech, the xx announced they would use the £20,000 prize money to build their own studio, where they subsequently wrote and recorded their second album Coexist. When Coexist debuted in September 2012, xx was still on the British chart at number 37 and had sold 446,734 copies in the UK. The following year, it was ranked number 237 on NME's list of the top 500 albums of all time and named the 74th greatest debut record by Rolling Stone, who found its music radical as "an exercise in restraint, in the artful use of space and silence" during popular music's period of maximalism.

In subsequent years, xx proved highly influential as many indie bands and mainstream pop acts incorporated the record's distinctive musical characteristics into their own songs. Petridis later wrote that to his surprise much of 2016's best-selling singles "sounded oddly but irrefutably" like the album: "You can hear its muted, echoing guitars on everything from the Chainsmokers' 'Don't Let Me Down' to Shawn Mendes' 'Stitches' to Zara Larsson's 'Lush Life'." Ryan Tedder, who wrote hit songs for such top-selling singers as Beyoncé, Taylor Swift and Ariana Grande, said the xx's "hauntingness" on the record "gets referenced in at least every other [writing] session".

By January 2017, xx had reached 562,400 copies sold in the UK, and in September 2019, its sales there were reported at 612,000. That same month, it placed 26th on The Guardian's poll of 45 music writers ranking the 100 best albums from the 21st century. In an essay accompanying the list, the newspaper's music editor Ben Beaumont-Thomas said the album features "the most compelling duets of the period: rather than singing to each other, it was as if two people were going through the same thing without the other knowing it – the perfect mood music for the disconnected interconnection of dating apps and social media."

After xx was released, the xx toured Europe and North America through the end of 2009. Their first show in August was at Hoxton Hall in London, which Sim recalled was attended by only 112 people. When Pitchfork's positive review of the album elicited greater interest among American listeners, the xx were booked as the supporting act for the Friendly Fires's tour of larger club venues in the US. The difficulties of touring early on exacerbated the growing tensions between Qureshi and the rest of the group, which culminated in her dismissal after a difficult stay at an October music festival in New York. It was reported that she had become fatigued and left the group after they cancelled several concerts. Sim disputed those reports and said her departure had been the band's decision: "We've grown up to be very different people. It wasn't working any more musically or as a friendship." Croft told NME in November, "I guess 'personal differences' would be the standard way to say it. I guess it's just the intensity of being on tour, things are so much heightened."

Rather than find a replacement for Qureshi, the xx continued to tour as a smaller line-up of guitar, bass and percussion. They also reduced their already minimalist arrangements for songs in concert, although Sim jokingly said Smith "needs another few arms so he can work everything" after Qureshi's departure. In their shows, Croft abandoned playing solos and chords in favour of less defined figures and motifs, while Smith performed beats and ambient sounds from his synth pad as an accompaniment to Croft and Sim's playing. Because their style had been suited to the small venues they first played, the xx focused more on the production value of their concerts and performing for larger audiences while on tour. They dressed in dark clothing and illuminated the stage with light boxes displaying their x-shaped, white-on-black logo.

With a growing fanbase, the xx made commitments to more concerts and extended their tour for the album. They toured intermittently for 18 months, including most of 2010. That year, they embarked on their first US tour and played high-profile festivals such as South by Southwest, Coachella and Bonnaroo. They were also a supporting act for fellow English group Florence and the Machine. Recalling the xx's show at Coachella, where they performed for 30,000 people, Croft said: "That was the moment when I was, like, Oh, my God, I think people might be into this."

By touring frequently, the xx broadened their reputation among listeners and the press. In March 2010, they played two consecutive nights at the Shepherd's Bush Empire in London to capacity crowds and appeared on the cover of NME, who proclaimed them "the most underrated band in Britain". In April and May, they toured the southern US and Japan, which Croft said was most demanding part of the tour because "none of us had been away from home continuously for so long." They were accompanied during this six-week period by the photographer Jamie-James Medina, who later published his photos of the group in his book The Tourist (2010).

While on tour, the xx acclimated themselves to the increased attention and became considerably more sociable and confident. As Sim recounted, "If you'd have put me onstage at London's Shepherd's Bush Empire a few years ago, I'd have run away. I couldn't have done it. We used to be terrified." In June 2010, the band played the Glastonbury Festival in Somerset and, according to the journalist Jude Rogers, displayed a newfound confidence through the rest of their summer and "post-Mercury [Prize] autumn" concerts: "Croft would sing more boldly, Sim developed an onstage swagger and Smith began experimenting with different rhythms and textures."
