Tonight’s benefit for the Washington Free Clinic features D.C. acts Velocity Girl, Lorelei, Tone, and Chisel. Think of it as a locally oriented festival concert, with the proceeds going to a more worthy recipient than, say, some whiny radio station. At 8 p.m. at Radio Music Hall, 9th & V Sts. NW. $8. (202) 393-0930. (Steve Kuhn)
