Anticipation for the 2015 Bonnaroo Music and Arts Festival skyrocketed among fans today when Bonnaroo announced they will reveal the lineup for the June festival on Tuesday, Jan. 13.

This surprise lineup reveal is weeks before the original reveal date, scheduled for late February.

Bonnaroo also announced they will let fans reveal the lineup for the festival.

Those calling 1-844-ROO-2015 (1-844-766-2015) on Tuesday, Jan. 13, between 6 p.m. and 9 p.m. Eastern time will be given the name of an artist who will be performing at this year’s festival. Fans can then share the artist’s name on Facebook, Instagram and Twitter with #Bonnaroo.

This unconventional lineup reveal follows Bonnaroo’s “12 Days of RooClue,” in which the festival posted a photo each day giving a different clue about the artists who might perform this year at Bonnaroo.

Among the artists alluded to by these clues were Led Zeppelin lead vocalist Robert Plant and Bonnaroo veterans Yonder Mountain String Band.

California music festival Coachella also revealed their lineup early with artists Jack White, Drake and AC/DC headlining the three-weekend event.

In Coachella’s case, tickets went on sale on Wednesday, Jan. 7, and sold out within a day. Could Bonnaroo be jumping the gun with their lineup reveal? Announcing the lineup this early may put the artists at greater risk of not being able to perform due to unforeseeable conflicts.
