Oakland-based “pagan lounge ensemble” Rosin Coven took the grand prize last night in the 2007 Independent Music World Series’ West division. A showcase at SF club The Independent featured the national contest’s top six bands from the western United States, also including San Francisco’s the Tongues, and Rosin Coven walked away with grand prize honors to be shared with regional winners from the Southwest, Southeast, and Northeast. Rosin Coven will receive a cash award, gear for a home studio, a CD manufacturing package, studio time, showcases at popular music conferences, appearance on an IMWS compilation, and more. The band’s eight members — on violin, cello, bass, guitar, harp, vibraphone, drums, and vocals — perform a dark, theatrical cabaret blending jazz, classical, and Latin styles. Give ’em a hand for scaring away the competition.
