You don't have to be a Sufi mystic or student of Pythagorean tonal theory to dig Secret Chiefs 3, but it helps. Brainchild of multi-instrumentalist, occultist, and genius Trey Spruance, the nine-piece collective smashes trance-inducing Middle Eastern song structure, tuning, and instrumentation with stabs of death metal, surf jazz, and electronic deviance, making modern traditional music as bazaar as it is bizarre. Recommended if you like Ennio Morricone, Mr. Bungle, or opium binging. (Neumo's, 925 E Pike St, 709-9467. 8 pm, $12, 21+.)
