Be sure to tie the flannel tightly around your waist for tonight’s evening of ranking, skanking, and stage diving, as three of the better pop-punk acts come moshing into town. On opening act Swingin’ Utters’ A Juvenile Product of the Working Class, tracks like “London Drunk” and “The Black Pint” blend the sound of the Pogues and a million ’77 Britpunk outfits into a melodic bender. The Bouncing Souls are ’80s fetishists, endlessly celebrating their youths, while reformed headliners Descendents are the genre’s grandpappies, though they’ve never grown up; unrequited love and gastrointestinal difficulties are still these thirtysomethings’ main concerns. At 7:30 p.m. at the 9:30 Club, 815 V St. NW. $10. (202) 393-0930. (Christopher Porter)
