When I was a kid, going to summer camp meant sleeping on moldy cots, guzzling Tang, and failing year after year to pass a swim test in the deep end of the lake. Campers at Girls Rock! DC have it way better: The young aspiring musicians learn to write killer hooks, spin dance tracks, and melt tweenage faces on electric guitar. To raise financial-aid funds for this summer’s program, GR!DC is hosting an all-star line-up of local female musicians at U Street Music Hall. The magnetic, crowd-charming ladies of Be’la Dona (D.C.’s only all-female go-go band, shown) and emerging live-looper vocalist Margot MacDonald will join Black Alley, the Coolots, and other homegrown talent for a salute to the community-building, confidence-boosting power of rocking out. If you’re too old to sign up for GR!DC camp yourself, this benefit show is a pretty decent consolation prize. The concert begins at 6 p.m. at U Street Music Hall, 1115 U St. NW. $20–$25.
