Riot Fest comes to May Farms in Denver, Colo., on Sept. 21-22 with a slew of top-name acts in tow, and Diffuser.fm and Loudwire are stoked to be giving away five pairs of two-day passes. Enter via the widget above.

The big story at Riot Fest 2013 is the Replacements reunion, and while seeing Paul Westerberg rock alongside Tommy Stinson is reason enough to go, the festival also features Blink-182, Iggy and the Stooges, Rancid, Best Coast, Guided By Voices, Against Me!  Yo La Tengo and dozens more raucous rock 'n' roll bands. Click here to gawk at the rest of the roster. There are even carnival rides and a corn maze, just in case you were on the fence.

Enter above for your chance to win a pair of tickets to this must-see event. The contest runs until Aug. 29 -- click here for a full list of rules. Note: The prize does not include airfare, accommodations or other travel expenses. We'll get you in to see the 'Mats and the Pixies and all the other great bands, but outside of that, you're on your own! And if you don't live near Denver, fear not: Riot Fest hits Toronto on Aug. 24-25 and Chicago on Sept. 13-15.
