One of fall’s best lineups features three bands with starkly different interpretations of indie pop: TEEN (with D.C.’s own Carpark Records) makes spare, danceable new wave, while Widowspeak delves into hazy ’70s nostalgia. But Ava Luna is the sleeper draw of the evening: The band’s genre-defying mix of slinky R&B and dissonant post-punk translates into tense, thrilling live sets. Read more in our Fall Arts Guide. Teen performs with Widowspeak and Ava Luna at 9 p.m. at Comet Ping Pong, 5037 Connecticut Ave. NW. $12. (202) 364-0404. cometpingpong.com. (Maeve McDermott)
