Fans hang out outside the Congress Theatre at the 2007 Riot Fest. This year they can be outside for two days of the festival, at Humboldt Park.
Chicago will be rocking out all summer, and well into September, thanks to Riot Fest and Carnival.
Organizers have unveiled the lineup for the annual festival, scheduled for Sept. 14th at the Congress Theater and Sept. 15-16th in Humboldt Park.
This year's headliners include Rise Against, Iggy & The Stooges, The Offspring and Elvis Costello. (View full lineup)
It's the first year that a portion of the festival will be held outdoors. The festival grounds will encompass Division to North and California to Sacramento in Humboldt Park.
Three- and two-day passes are available for $36-$155 and single-day tickets will be available soon.
