The 2015 edition of Bonnaroo festival will run from June 11-14 in Manchester, Tennessee.

The diverse line up for this year’s event surfaced via unconventional means, with fans calling 1-844-ROO-2015 to learn the name of one act on the bill before subsequently sharing it on social media with the hashtag #bonnaroo.

So far, it has been confirmed that Kendrick Lamar, Slayer, Spoon, Flying Lotus, Run the Jewels, Belle and Sebastian, the War on Drugs, Mac DeMarco, Caribou, Florence and the Machine, Freddie Gibbs and Madlib, Shabazz Palaces [pictured], Jamie xx, Earth Wind and Fire, Robert Plant, Rustie, Tycho, SZA and more will perform.

There will also be a performance of William Onyeabor’s music by the Atomic Bomb! band, which features David Byrne.
