Riot Fest Denver  is, in my opinion, one of the best looking festival lineups of the year.

The event takes place in a giant field near Byers, Colorado September 19-21.

Headliners include Rise Against, Weezer, Social Distortion, Slayer, Primus, Subline, The Cure, and Wu-Tang Clan.  Some other great bands to see include A Day To Remember, Dropkick Murphy's, Bring Me To The Horizon, Clutch, and NOFX.
