The xx will headline at next summer's Cornish music event the Eden Sessions.
The band, who released their second studio album Coexist this September and hit the top of the UK album charts, will top the bill at the Eden Sessions on Tuesday 2 July 2013.
Coexist follows the London trio’s self-titled platinum-selling debut album which won the Mercury Music Prize in 2009.
Last year they were nominated for three Brit awards for their distinctive understated ambient indie pop sound.
They have a reputation for powerful live performances and their show at this year’s Bestival drew what is said to be the largest crowd in the history of the festival.
Martin Williams, Eden Project Marketing Director, said: “We are thrilled to be able to announce an act of such a high calibre for the 2013 Eden Sessions. We’re very excited to be hosting The xx, especially considering that we are one of just a handful of summer gigs they will be playing.”
Announced as a Sessions headliner earlier this year, Eddie Izzard will be bringing his Force Majeure show to the home of the Biomes on 3 June, 2013.
The Eden Sessions will have been going for 12 years next July. Previous headliners include Blink-182, Plan B, Tim Minchin, Chase & Status, Noah and the Whale, The Vaccines, Example and Frank Turner.
