For an art opening act, check out this photography show at Good Children Gallery. In 1979, years before winning numerous awards (including two Pulitzer Prizes) as a staff photographer at The Washington Post, then-26-year-old intern Lucian Perkins captured a series of hardcore concerts by what soon would become titans in the capital city's embryonic rock community: Bad Brains, Trenchmouth, Teen Idles and the Untouchables. Collected in a photo essay and traveling exhibition, Hard Art DC 1979 frames you-are-there images of baby brothers Ian and Alec MacKaye — then 17 and 14, respectively — as accidental tourists of D.C.'s enduring musical legacies, and it bares witness to the screaming birth of punk. An after-party at Siberia (2227 St. Claude Ave.) features New Orleans acolytes Die Rotzz, Classhole, Gasmiasma and Vapo-Rats. Call for ticket information. — Noah Bonaparte Pais
