What with the recent advent of the Coachella lineup, it's officially festival announcement season! Bonnaroo is the next to join the fold, confirming their 2015 lineup yesterday by having fans call in to learn one artist's identity, then peruse the #bonnaroo hashtag to discover what other fans had learned. Now they've posted the complete lineup and poster for those with phone anxiety - it's great, with Kendrick Lamar sharing top billing with Billy Joel. Belle and Sebastian, Spoon, the War on Drugs, Flying Lotus, Caribou, Mac DeMarco, Courtney Barnett, Shabazz Palaces, Iceage, and more round out the rest - peruse the whole lineup in the poster above. It's all going down June 11th through 14th in Manchester, Tennessee.
