After months of rumors, the Lollapalooza 2011 lineup has been announced. Topping the bill are Eminem, Foo Fighters, Coldplay, Muse, My Morning Jacket, deadmau5 and A Perfect Circle.

The festival celebrates its 20th anniversary this year, and after several coast-to-coast outings and some six years off, it now calls Chicago's Grant Park home. Early bird tickets for the August 5-7 show went on sale on March 29 and sold out swiftly. Three-day passes, VIP and travel packages are still available and a limited number of single day tickets will go on sale June 7. Other acts scheduled to perform include Cee Lo Green, Damian “Jr. Gong” Marley & Nas, The Cars, Ween, Bright Eyes, Arctic Monkeys, Big Audio Dynamite, Girl Talk, Kid Cudi, Crystal Castles, Flogging Molly, Cold War Kids, Grace Potter & The Nocturnals and Lykke Li. Lollapalooza founder and Jane's Addiction frontman Perry Farrell will also be making a performance on his signature stage under the moniker of PerryEtty vs. Chris Cox. “Muscular beats -- that’s the theme," said Farrell in a statement. "Our new tent houses fifteen thousand people at once.” For the full lineup and a retrospective interactive Lollapalooza time capsule , check out the festival's official site.
