Bonnaroo organizers were planning to unveil the festival’s 2016 lineup on Conan next week, however, it appears a premature leak has stolen a little luster from the forthcoming announcement.

The majority of the roster -- save the headliners -- accidentally appeared on the Bonnaroo app last night (Jan. 13). Among the artists included in the leak are Ween, M83, Tame Impala, Haim and Father John Misty. And though the headliners didn’t show up on the app, Consequence of Sound reports they are Pearl Jam, LCD Soundsystem and Dead & Company (the band comprised of Grateful Dead members and John Mayer as frontman).

When CoS reached out to Bonnaroo for comment on the leaked lineup, a representative neither confirmed nor denied its accuracy: “I love this time of year, it is always filled with anticipation and speculation. As you know, we will be releasing our official lineup [on] the 19th on Conan. The show is going to be a good one.” You can watch the Conan promo at the top of the page.

Bonnaroo will take place from June 9-12 in Manchester, Tenn. Passes go on sale next week.
