Nasher Museum AuditoriumPamela Z’s altered vocal constructions owe a debt to the 1970s Kitchen scene of Soho New York, where Meredith Monk and Charlemagne Palestine turned their voices into avant instruments. Similiarly, Z twists air through processors and objects, controlling textures and timing with a synthesizer worn over several muscles. The result is playful and bewitching. This kicks off UNC-Chapel Hill and Duke’s Milestones Festival of New Music, which runs through Wednesday. For more, see www.duke.edu/web/dukeperfs. Tickets are $18 and the show begins at 8 p.m. Grayson Currin

Common Ground TheaterOne doesn’t expect to hear the 3/4 timekeeping of the tango out in the woods between Durham and Hillsborough, but that’s what’s happening tonight. Co-sponsored by our 2006 Indies Arts winner Tangophilia, there’s an 8 p.m. lesson for the newbies before the reveling starts at 9 p.m. Admission is $5-$7, and there’s a cash bar. For directions, visit www.cgtheatre.com. David Fellerath
