Tom Petty and the Heartbreakers will headline on Saturday, July 19th; Dave Matthews Band will top the bill on Sunday, July 20th. Colorado has never before seen a music festival of this magnitude: hosting five stages (some tented), food from many of Denver's top restaurants, an artists' village, misting tents and more.

In addition to the headliners, performance highlights include John Mayer, The Black Crowes, Mike Gordon, O.A.R., Michael Franti & Spearhead, Rodrigo y Gabriela, Steve Winwood, Spoon, Jason Mraz, Flogging Molly, Colbie Caillat, OneRepublic, The Roots, Lupe Fiasco plus local favorites Flobots, Rose Hill Drive, Meese, Born In The Flood, Railbenders and The Photo Atlas.
