This Friday, Washington City Paper is hosting the next installment in our all-ages, free concert series at the Luce Center at the Smithsonian Museum of American Art. If you’ve never come through to one of our shows, you’re missing out: It’s a gorgeous space—skylights, intricate tile-work, balconies full of artworks—and a rare chance to see some of D.C.’s best music acts in a small, casual, early-evening crowd.

First up on Friday: Art Sorority for Girls, a charming indie-pop outfit whose latest release, an intimate, earwormy record called Older Boys, made our list of 2014’s best local albums. Art Sorority frontman and songwriter Daoud Tyler-Ameen (above) will perform backed by Rosendo Flores (of Möbius Strip and Aloners) on drums.

Neo-soul/rock group lowercase letters (below) will follow, playing from their new self-titled album, which melts into slow-burning grooves as easily as it bursts into driving dance numbers. Singer Alphie Williams will lead the outfit’s sultry beats with her hefty, confident melodies.

Listen to Art Sorority for Girls and lowercase letters after the jump, and come out to the (free! all-ages!) show at the American Art Museum at 6 p.m. sharp this Friday, Feb. 6. There will be snacks, too, and free beer tastings from Alexandria’s Port City Brewing Company.
