alt-J are one of the most successful British bands of the decade. They are currently working on their third studio album, the follow-up to the number one, BRIT and GRAMMY nominated ‘This Is All Yours’, and their Mercury Prize and Ivor Novello Award-winning debut ‘An Awesome Wave’. Between them, the two records have sold in excess of two million copies and their songs have been streamed more than one billion times. The band have headlined festivals across the globe and sold out London’s The O2 and New York’s legendary Madison Square Garden on their last tour. We’re honoured to have them back at the tent to help us celebrate our tenth birthday.
