The time has arrived. The three-day festival kicks off at Grant Park in Chicago on August 2, touting a lineup that includes Phoenix, Vampire Weekend and The Killers as well as The Cure, Nine Inch Nails and Queens of the Stone Age. The festival, which runs until August 4, is already sold out, but the event promises some baller performances—last year featured The Red Hot Chili Peppers, Black Sabbath, Jack White and dozens more. Here's a mix of songs from artists touching down in Chi-town.
