In the age of festival lineup announcement videos, Bonnaroo is trying something a bit different, and putting the power in the hands of the fans.

This year, Bonnaroo is inviting the fans to announce the bands while they watch a sneak peek of the Skrillex SuperJam Documentary and more great performances from The Farm. The event is called BLAM! (Bonnaroo Lineup Announcement Megathon) and will take place on Tuesday, January 13th. Here's how it works:

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. Be sure to 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.
