Secret Chiefs 3 performs "The End Times"

The unclassifiable and somewhat mysterious Bay Area combo Secret Chiefs 3 are a known delicacy for those with ears for the offbeat. The brain child of former Mr. Bungle guitarist Trey Spruance, the Secret Chiefs display a knack for juggling genres as disparate as psych, techno, soundtrack, avant-jazz, experimental cut and paste and death metal, along with an acute taste for absurdity and a fascination with religion, philosophy and various iconography. The band’s ever shifting lineup and unorthodox approach to making records has undoubtedly helped to keep their work fresh. All in all, it makes for a glorious art project. The band’s tour, with support from the similarly enigmatic Oakland-based group Sleepytime Gorilla Museum, stops at the Tralf this Monday.
