Riot Fest Chicago will be held in Douglas Park from Sept. 11-13. Some bands scheduled to play Denver will also perform at Chicago's outing, but it will also feature heavy hitters such as Faith No More and No Doubt. A second wave of performers will also be announced soon.

The third and final Riot Fest of 2015 will take place Sept. 19-20 in Toronto and will be headlined by Ontario natives Alexisonfire. Further acts confirmed include Wu-Tang Clan, Against Me! and Motorhead. Fans can expect a second wave of acts to be announced on June 16.
