The initial list of bands playing Chicago's 2013 Riot Fest has been unveiled and it features a number of prominent punk, rock, alternative and metal acts. Fall Out Boy and Blink-182 are two of the three headliners, with the third act a mystery as of now.

The three-day event, taking place Sept. 13-15 in Chicago's Humboldt Park, will also feature such bands as Violent Femmes, Motorhead, Rancid, AFI, Sublime With Rome, Pierce the Veil and the Devil Wears Prada, among dozens of other acts.

The diverse lineup ranges from GWAR to Blondie, with veteran acts like Public Enemy, Guided by Voices and Bad Brains playing alongside younger bands that are just starting out.

More acts will be announced shortly, but tickets for Chicago's Riot Fest are already on sale. Prices started out at $69.98 for a three-day pass, but have gone up as more and more people purchase tickets.
