While most music lovers in Chicago were preoccupied with a certain other festival over the weekend, Riot Fest announced some big changes to the lineup for its Sept. 13-15 affair in Humboldt Park.

The festival announced Friday that Pixies, Joan Jett & the Blackhearts, Suicidal Tendencies, Andrew W.K. and T.S.O.L. were among a number of new additions to the festival's impressive lineup, which already includes the Replacements, Fall Out Boy, Blondie, Public Enemy and many more.

Meanwhile, while three-day passes to the fest/carnival are already sold out, one-day passes are set to go on sale Wednesday. Day-by-day lineups were also unveiled Wednesday.

In honor of the news, HuffPost Chicago has partnered with Riot Fest to offer up another pair of three-day general admission passes to the event.

The contest has now closed and the winner notified. Thanks for playing! We'll be giving out more tickets to live music events before summer's end.
