Last night, Tuesday, April 19, Method Man, Redman and Raekwon kicked off the Red Rocks season and 4/20 celebrations with 4/20 Eve on the Rocks. The event featured a relatively diverse lineup, starting in the afternoon with Boulder-based stringed hip-hop trio Whiskey Blanket and continuing with reggae band Stick Figure, whose set featured a dog on stage. As the sun went down, the seats filled up and the smoke settled. Here's a look at the music lovers of 4/20 Eve on the Rocks, and what they get up to. All photos by Brandon Marshall.
