The xx play new material at Sweden's Hultsfred festival
Noel Gallagher's High Flying Birds also appeared at the final day of the event and The Cure played until 4am
Opening with a stripped-back and minimal new track, the trio moved through an hour-long set, interspersing new and old material and offering up a re-worked, slowed-down version of 'Crystallised'.
The band were greeted with fervent cheers throughout and seemed assured and confident in their set, with co-vocalist Oliver remarking: "I can't tell you how nice it is to play new songs; it's been a long time."
Last month, the band played their first shows of the year in London, debuting many of the same tracks and finally shedding light on the follow-up to their Mercury Prize-winning debut. 'Coexist' will be released through Young Turks on September 10th.
Saturday also saw Noel Gallagher's High Flying Birds play an anthemic, late-night slot which ended with a rousing sing-a-long of 'Don't Look Back In Anger'.
Mumford and Sons were due to headline the last night of the festival, but were forced to cancel after Marcus Mumford broke his hand. They were replaced last minute by The Magic Numbers, who drew a small crowd.
The previous day offered up a number of stand-out performances across the festival's four stages. Kasabian smashed the main stage with an early evening, hit-laden set drawn from across their four records, culminating in a giant mosh pit to 'Fire' and singer Tom Meighan serenading the crowd with The Beatles' 'She Loves You'.
Later that night, The Cure played an epic three-hour set that finished in daylight just before 4am. "I'd like to carry on playing until the sun is completely up, but the police are going to pull the plug," smiled Robert Smith from the stage, before ending with 'Boys Don't Cry' to a 500-strong group of fans who had remained for the whole set.
The Cure will continue their string of European festival appearances throughout the summer before returning to the UK to headline Reading And Leeds Festivals.
