Riot Fest 2013 has added several bands, and lost a few others.

A handful of bands have been added to the previously announced lineup for the 2013 Riot Fest, which will take place September 13, 14, and 15 at Humboldt Park in Chicago, IL. Among the new additions are Hatebreed and Suicidal Tendencies, while Motorhead, Bad Brains, and Attack Attack! have dropped off the fest. Here's the official word:
What could possibly make 2013's Riot Fest & Carnival any better? How about a few more bands! Pixies, Joan Jett & the Blackhearts, Suicidal Tendencies, Andrew W.K., Hatebreed, T.S.O.L., Off With Their Heads, The Flatliners, Nativ, Hostage Calm, The Interrupters, New Beat Fund, and Pet Symmetry will all be joining us this September to round out this rock and roll carnival! Regrettably, a few bands have had to cancel due to unforeseen circumstances. Motörhead, Bad Brains, and Attack Attack! will not be able to make it this year. Keep an eye out for the daily schedules and individual day passes for all of this year's Riot Fests Wednesday, July 24. A limited amount of 3-Day Passes are still available, but they're going fast. Under two months to go, we'll see you at the show!
