A lineup of legendary bands took the stage on the first day of Denver's inaugural Riot Fest at May Farms
in Byers, Colorado. Guided By Voices, AFI, Iggy and the Stooges, and The Replacements were among those who played. Couldn't make it? Our photographers were on the scene. Images by Aaron Thackeray or Eric Gruneisen unless otherwise noted.
