There is something positively hypnotic about Odor of Pears, an enticing air of gloomy sensuality.  With electronic hums, gurgles, and bangs circling chilly crooning, the East Bay trio's recent self-released "Crown of Thorns" CD brings to mind floods of shadowy reminiscenes:  Siouxsie and the Banshees meet Dead Can Dance, the Sisters of Mercy meet Laurie Anderson, a new wave band meets its doom.  DJ's Christine Death, Cutter, and Kermit spin goth, industrial, and 80's rock before and after the show.  (S.H.) 8 pm.  Driftwood, 1313 Park St., Alameda. 522-5141
