Since his debut in 1991, New York-based artist Matthew Barney has conducted a multimedia exploration of his own body through performances, photographs, drawings, sculpture and, most recently, the controversial "Cremaster" video series. "Cremaster 5," the latest in the series, has its West Coast debut this weekend at the Nuart. In the operatic Gothic-style romance, Barney explores themes of biological transformation, taking on the multiple roles of a magician, a diva and a giant opposite actress Ursula Andress. Photographs and drawings made during the filming of "Cremaster 5" open Saturday at Regen Projects.
