Bonnaroo 2011 Headlined By Eminem, Lil Wayne, Arcade Fire

Wiz Khalifa, the Strokes, Mumford & Sons and the Black Keys also set to appear at Bonnaroo.

On Tuesday (February 15), organizers announced the lineup for the 2011 Bonnaroo Music and Arts Festival, set for June 9-12 in Manchester, Tennessee. And, boy, it's going to be interesting to hear the purists' take on this year's bill.

Unlike earlier, decidedly crunchy editions of the fest, the 2011 lineup is topped by two of the hugest hip-hop acts in the business — Eminem and Lil Wayne — along with newly crowned [article id="1657879"]Grammy champs Arcade Fire[/article] and the Black Keys. Other acts on the bill include Mumford & Sons, the Strokes, the Decemberists, Florence and the Machine, Big Boi, Wiz Khalifa and Robyn.

Of course, there are still some nods to Bonnaroo's roots: Fest vets Widespread Panic return once again, as do My Morning Jacket and the String Cheese Incident. Also doing their part for the traditionalists out there are reunited legends Buffalo Springfield (in their only festival performance), Robert Plant and the Band of Joy, and Dr. John and the Original Meters, who will perform their 1974 album Desitively Bonnaroo, from which the festival took its name.

As in previous years, there will be an epic super-jam, this one organized by Dan Auerbach of the Black Keys and Dr. John.

Other artists set to appear at the 10th annual Bonnaroo include Ray LaMontagne, Iron and Wine, Girl Talk, Primus, Explosions in the Sky, Deerhunter, the Walkmen, Sleigh Bells and Smith Westerns. All in all, some 150 bands will perform at this year's fest.

Tickets for Bonnaroo 2011 go on sale Saturday, February 19 at 12 p.m. ET through the festival's official website.
