The xx exist in a time and space of their own making. In 2009 the south London trios debut album xx, quietly made at night over the course of two years, bled steadily into the public consciousness to become shorthand for newly refined ideas of teenage desire and anxiety. Articulated with a maturity beyond their years, its hallmarks were restraint and ambiguity. In the age of the over-share, xx was pop with its privacy settings on max.Three years on, Romy Madley Croft, Oliver Sim and Jamie Smith are back with a new album, Coexist, and a new perspective. Where xx lent in close to whisper in your ear, Coexist gazes warmly in your eyes. Much has happened to lead to this point: most pertinently, theyve grown up.Following the release of xx, the trio spent the lions share of 2010 far from home, taking their gentle shaping of a new London sound to ears and hearts in America, Japan, Australia and mainland Europe. Critical acclaim was matched by commercial success around the world, before The xx won the UKs prestigious Mercury Music Prize. With all the successes and new experiences of that intense year and a half, a period away from the stage and studio was inevitable. In late October 2010 The xx returned from tour for some time apart, and normality.All of our friends had been to university and left home, says Romy. We really wanted to do that natural thing that you do when you go to uni or grow up. All three moved out of their family homes within two weeks of being back. They made up for lost time with friends, hung out and embraced a summer of festivals and shows that Jamie was booked to DJ. We were his groupies, laughs Romy.Previously cast as the quietest of the three, Jamie became the public face of The xx in 2011. In-between DJ gigs, he focused on growing his production skills, developing a distinct sound and presence. His remix of Adeles Rolling In The Deep, re-imagining of Gil Scott-Herons final album on Were New Here with its defining single Ill Take Care Of U, and his debut solo single Far Nearer set him apart as a highly regarded producer in his own right. That position was cemented when Drake asked Jamie to produce the title track of his album Take Care, inspired by Ill Take Care Of U.Behind the scenes, there was evolution too. Romy and Olivers writing process on xx had been to exchange lyrics over the internet and only sing what they each had written. Having begun to write again quite soon after returning from tour Much sooner than I expected, says Romy they discovered that their initial reticence to bare so much of themselves in person had faded.The newest thing that weve done on this record is that me and Romy wrote in a room together, explains Oliver. We went into a room with nothing and talked through early ideas together, which was fun but bizarre because weve never done that before. I also sang one of Romys lyrics for the first time, which felt really nice.Where dreams and expectation had largely coloured Olivers lyrics on xx, on Coexist he draws on his own experiences: Which Im surprised Ive done because I knew people were going to hear them; Im surprised I was able to put it out there confidently. Conversely, Romy wrote quite openly from experience on their debut: It felt very much like a direct diary although obviously weve always written quite cryptically. I think my lyrics have become more from observation and expectation, which is a complete swap.That realignment extends to Jamies role. When he originally joined the band theyd been writing and gigging for a year. This time around it was the three of them working together from the start. Following a short spell in a Dalston practice room, Jamie found a space in Angel that would become their studio. Essentially a couple of rooms in an ordinary office block, they turned the once mundane space into a nocturnal hub of creativity among the nine-to-five surroundings, hanging black velvet on the walls as soundproofing and fitting it out with a set-up that now included piano, drums and steel pan. Back together again, separate from both their label in west London and east Londons music scene, Romy, Oliver and Jamie wrote Coexist.We just ended up playing new stuff to each other to try and write which was a fun way to do it, explains Jamie. It wasnt always plain sailing: The idea I had at the beginning when we started wasnt the right idea because Id been in a place where I was making music for Drake and other people, and myself, and Id kind of forgotten about working with these two, which is very different because were so close. Jamie continues: Learning to work together as grownups was the biggest thing its the thing that influenced the album the most. We just needed to find a balance.Understanding that balance became the heart and soul of Coexist. Jamie has done his solo stuff and Oliver and I have done separate things but The xx is only when were together. Thats when its really us, explains Romy. I was reading up on oil on water when you see a puddle on the floor and its a rainbow. Oil and water dont mix, they agree to peacefully coexist. I really liked that these two simple things, oil and water, that together make something beautiful.To coexist doesnt paint the rosiest picture but I think it represents the realness, continues Romy. Learning to live together, learning to work together again, learning to live with the person youre with, or your ex. Its all connected. Through that learning process, the anxious night time of xx has made way for sunrise on Coexist.While the fingerprints of R&B remain, Coexists dawn realisations flicker into life under house musics gaze, most resonant on Reunion, Sunset and Swept Away. It also echoes in Romys guitar riffs and Olivers bass lines, which circle and build like loops. Thats something I love about dance music, how something insignificant can somehow become profound after the fifth repetition, says Oliver.Above all, though, Coexist is an album of confident adult reflection. Angels, sung by Romy, is a perfectly distilled love song. Its counter is Fiction led by Oliver, a bittersweet ballad thats strength lies in naming its fear. What has changed for The xx? Nothing, and everything. Older and wiser, surer yet still so tender, Coexist finds itself on the other side of heartbreak, when the light returns.
