Before each show, members of the Forestville, Md., rap trio Gods’Illa greet the crowd shouting “Peace!” Their music, a blend of insightful, optimistic lyrics and percussive instrumentals, harkens back to hip-hop in the 1990s, when MCs could still sell records speaking to civic unrest. That’s part of why Gods’Illa (pictured) is such an apt choice for the D.C. Peace Festival, a benefit concert for the local prostate cancer awareness group Pro-Seeds Project. But it’s ironic, and perhaps telling, that the concert is being held at DC9, where in 2010 five employees were charged with killing Ali Ahmed Mohammed. Though the charges were dropped, the incident ignited the local Ethiopian community. Could the D.C. Peace Festival help fund prostate cancer research and soothe local tensions in one evening? It’s worth a try.

Louder Than Quiet, Gods’Illa, Phil Adé, Skip Mahoney and the Casuals, host Enoch 7th Prophet, and others perform at 6 p.m. at DC9, 1940 Ninth St. NW. $10. dcpeacefestival.com. (774) 277-9202.
