In addition to all the witchy happenings tonight, there will also be a most spectacular showcase of avant garde music video art and performance. The lineup for “We’ll Do It Live” reads like a who’s who of video art, so if this stuff turns you on at all, you probably won’t want to miss one of the more interesting and under-publicized performances at Trinity Rep’s Pell Chaffee venue. $10 with student ID (also discounts for teachers, fire fighters and police)$15 otherwise at the door Featuring:Richard Devine, Brian Kane, Nalepa, Duncan Laurie, Aerostatic, David Last, VJ Benton C, Robotkid and Todd Thille
