Organizers of the annual music festival Lollapalooza, held in beautiful Grant Park, Chicago, have graced fans with the daily schedule grids which detail the hundreds of performances for fans to enjoy during the three-day event.

Headliners Eminem, Foo Fighters, Coldplay, and Muse will be on hand to help fans celebrate the festival’s 20th Anniversary.

Organizers are hoping for outrageous and exciting performances from its acts to show other music festivals that Lollapalooza knows how to party. With the success of Eminem and Foo Fighters’ recent album releases and the dramatics of Coldplay and Muse, Lolla will have a little something for more than just the hipsters this time around.

Since it is the 20th Anniversary, who knows what the head honchos will surprise guests with— perhaps a surprise duet between Rihanna and Eminem for “Love the Way You Lie” or maybe Thom Yorke of Radiohead joining Chris Martin from Coldplay on a song or two?

Something HAS to top last year’s bare breasted crowd surfing by Lady GaGa, and Arcade Fire’s sick renditions from their album ‘The Suburbs’.
