Dreamy, restless, and dripping with cool, Brooklyn-based soul-pop act Ava Luna transformed itself from a grand seven-piece group to a five-piece ensemble between its first two albums. Following that transition, the group’s ever-inventive tunes have evolved from experimental piano and acoustic guitar to gilded hi-fi vocals and accessible melodies. That’s not to say Ava Luna’s music was ever over-complicated—the roughness and complexities on its debut album, Lemming, made for a charming 2007 release, and the eccentric New Yorkers added a bit more rhythm on 2014’s Electric Balloon. Now, the group oozes confidence and sounds ready to find its new frontier on this month’s Infinite House. Drums boom on “Billz,” a percussion-heavy jam that incorporates mellow guitar with old-school soul vocals from singer Carlos Hernandez. Expect the crowd at Comet Ping Pong to bounce the band’s endless energy right back to the stage. Ava Luna performs with Young Rapids and Wing Dam at 9 p.m. at Comet Ping Pong, 5037 Connecticut Ave. NW. $12. (202) 364-0404. cometpingpong.com.
