“Art Saves” is a mantra for Otep Shamaya. When the Los Angeles-based artist/activist/vegetarian/lesbian decided to channel her deepest thoughts and aggressions into a musical project, she turned to her journals and illustrations. In less than a year, her “artcore” outfit Otep had generated major label interest and a spot at Ozzfest based on live performances alone. Originally reinforced by guitarist Rob Patterson, bassist Jason “eViL J” McGuire, and drummer Mark “Moke” Bistany, the self-described “intellectual loud mouth” and “equal opportunity dispenser of rage” has impregnated minds with brutal truths via five howling, message-filled albums (2002’s Sevas Tra, 2004’s House of Secrets, 2007’s The Ascension, 2009’s Smash the Control Machine, and 2011’s Atavist). Also on the bill: One-Eyed Doll, Butcher Babies, Howitzer, and Jane Doe. $19-$25; 7pm Fri, Sep 14; Backstage Live, 1305 E Houston, (210) 782-2817, dinproductions.frontgatetickets.com.
