Bonnaroo's promoters are taking the festival's big-reveal to the next level.
They're testing a so-balled "megathon" announcement, in which anyone keen to find out the names on the bill earlier than everyone else can do so. So long as they've got a phone line, a social networking account, and a whole lot of willpower.
Fans can call in to the 1-844-ROO-2015 hotline next Tuesday (Jan. 13) from 6pm to 9pm. One artist will then be revealed, and the caller must share the news via their social media page (Instagram, Twitter or Vine) with the #bonnaroo hashtag.
