Fall is almost here and for some, falling leaves and chillier weather might bring back nostalgic college memories of moody bands grooving on a makeshift stage. Luckily, Comet Ping Pong can return you to those grungy days with a triumvirate of moving, dreamy rock groups. Porches sets off the night with Aaron Maine’s darkly electronic and fuzzy ballads that grow deeper and more complicated as time goes on. He defines himself as “dark muscle” and it shows on somber and heavy songs like “Leather.” Where Porches stretches out its lyrics, co-headliner Witch Coast sounds choppier and more jarring. The trio touts no mastering, overdubs or production on its tracks. The vocals seem like they’re shouted underwater, conjuring memories of the sleepy angst you might have felt during a fall semester years ago. Porches performs with Witch Coast and Sitcom at 10 p.m. at Comet Ping Pong, 5037 Connecticut Ave. NW. $12. (202) 364-0404. cometpingpong.com.
