On Thursday, April 21, several diverse local acts— Chemtrail Pilot, Bud Melvin, Iceolus, Javelina, Cinik, and Blacker Guise (Alan George Ledergerber)—will form a circle. With the audience in the center, each will play one after another, around and around, until the result is one cacophonous improv session. The all-ages show happens at the Albuquerque Center for Peace and Justice (202 Harvard SE) from 8 to 11 p.m. Admission is by donation. (Jessica Cassyle Carr)
