Snowboard-video premiere parties have become big business in Denver and Boulder, with increasingly high-class and high-capacity venues, and sold-out crowds packed with pro-athlete VIPs. Our favorite of the bunch is Snowboard on the Rocks, an annual film-and-music extravaganza at Red Rocks Amphitheater presented by So-Gnar and Snowboard Colorado magazine. The fall event, now heading into its third year, combines live hip-hop performances with world premieres of the year's most hotly anticipated snowboard flicks. In September, Snowboard on the Rocks hosted the world premiere of TB:20, the twentieth-anniversary installment of Standard Films' Totally Board series, as well as the local premieres of Marc Frank Montoya's Familia 2 and the Videograss film Shoot the Moon, punctuated with performances by Doomtree, RJD2 and Michal Menert. That's a pretty sweet soundtrack for a September snow dance with 9,450 of your fellow shredders.
