KING FOR TWO DAYS Friday-Saturday: Renowned as one of the Twin Cities' busiest and most multi-faceted musicians, drummer Dave King will make a rare stab at staying put in one place all weekend -- albeit with five different groups, and at one of the loftiest performance spaces in town. His best-known jazz acts, piano/bass combo the Bad Plus and sax/electric-bass trio Happy Apple, will make an unusual co-appearance Friday alongside his improv group Buffalo Collision, featuring Plus pianist Ethan Iverson, saxman Tim Berne and cellist Hank Roberts. Saturday's lineup features two other debuts: Golden Valley Is Now, an electronica-fried trio with MVP keyboardist Craig Taborn and the Plus' Reid Anderson, plus the Dave King Trucking Company, a merging with Apple bassist Erik Fratzke, New York sax man Chris Speed and bassist Adam Linz that will drive home the all-star finale. (8 p.m. Fri.-Sat. $36-$40 both nights, $21-$25 each night. McGuire Theater, Walker Art Center, 1750 Hennepin Av. S., Mpls. 612-375-7600 or Also: King guests in the "Making Music" Q&A series at the Walker, 8 p.m. Thu., free.)CHRIS RIEMENSCHNEIDER
