Bonnaroo officials announced the lineups for three superjams going on at this year's festival. The superjams are Bonnaroo's way of getting things a little weird and finding out what happens. A huge host of musicians from diverse musical genres all take the stage at the same time to play the most jamtastical sets ever.

This year, the lineups are all over the place -- setting the stage, so to speak, for what could be an amazing show. Or that other thing -- the opposite of amazing. But probably amazing.

"SuperJam shows are about creating moments of surprise when no one knows what will happen next," producer Paul Peck said in a press release. "The amazing artists that are a part of the SuperJams are taking a big risk by stepping outside their comfort zones and doing something very ambitious in a very high profile performance. And they do it for the same reason we do: creating something special for the entire Bonnaroo community to experience together. We're all in it together and get to see what happens at the same time."

One lineup features Skrillex, the Doors' Robby Krieger and Warpaint. Another includes Derek Trucks, Andrew Bird and Ben Folds. And a third is a bluegrass jam hosted by 'The Office''s Ed Helms. You can check out the full schedule here.

At last year's superjam, R. Kelly surprised fans by showing up during My Morning Jacket singer Jim James' set. They delivered two Sam Cooke tunes -- 'A Change Is Gonna Come' and 'Bring It on Home.' Check it out in the video below.
