Bonnaroo has announced the details for its annual Bonnaroo Lineup Announcement Megathon, which is set to take place from 6-9pm on Tuesday, January 13. Things will be done a bit differently this year, as the festival has concocted a plan to let fans announced this summer’s lineup. Those that would like to participate are instructed to follow these three steps:

1. Call 1-844-ROO-2015 from 6-9PM EST to find out one artist on the lineup.

2. Share that artist on Instagram, Twitter or Vine. Use #bonnaroo so the whole world can see it.

3. Watch highlights from The Farm, including a sneak peek of the Skrillex SuperJam Documentary as the most creative fan announcements are chosen from social media to be on the BLAM! Feed at Bonnaroo.com.

Past Bonnaroo lineup announcements have featured appearances by Weird Al, Portugal. The Man, comedian Hannibal Buress and more. Last year’s festival included sets from Kanye West, Elton John, Jack White, Vampire Weekend, Lionel Richie, The Avett Brothes, Phoenix, Skrillex and Arctic Monkeys, among many others.
