Seattle quartet Zony Mash can't help recalling Medeski, Martin & Wood, but it's not a case of imitation so much as coincidence: two instrumentally gifted groups hitting upon a similar approach and manifesting their restlessly inventive jazz-funk sound in parallel time/space. Led by John Zorn–approved keyboardist Wayne Horvitz, Zony Mash can brood film-noirishly, groove swampily à la the Meters, and go bonkers on the astral-jazz plane. Tonight, they will have adventurous sax wildmen Skerik and Briggan Krauss in tow. (Tractor Tavern, 5213 Ballard Ave NW, 789-3599. 9 pm, $15, 21+.)
