SUNDAY

William Parker might want to investigate a time share in the District: The prolific bassist makes his third appearance here in five months. The previous two times Parker appeared in the area he played significantly different roles: As a member of the David S. Ware Quartet, Parker played the breakwater role, protecting listeners from the chaos of his leader’s titanic waves of sound, whereas at his solo gig, Parker moved up and down his four-string as adroitly as a guitarist, plucking and sawing notes in furious succession. Tonight, as the leader of his own quartet, In Order to Survive, Parker will demonstrate his unmatched ability not only as a player but as a composer. Join the band for a free pre-concert discussion at 6 p.m. at then settle back at 7:30 p.m. for a night of intense improvisation at George Washington University’s Marvin Theater, 800 21st St. NW. $12. (202) 232-5061. (Christopher Porter)
