Washington post-punk in all (well, much) of its variety comes together for tonight’s Positive Force benefit for the Glorious Church of God in Christ, a Richmond African-American church that was the target of arsonists. Included are the canny minimalism of the Warmers, the musically and politically direct style of the Suspects, and the poppier sound of Chisel. Also scheduled are the Shiny Brites. At 7 p.m. at First Congregational Church, 945 G St. NW. $5. (703) 276-9768. (Mark Jenkins)
