Considering the significant size of D.C.’s Iranian population, it’s not unusual to find prerevolution singers performing nostalgic gigs at venues throughout the city. Artists like Googoosh, whose popular blend of classical Persian intonation, Europop, psychedelia, and funk bridges both sides of the revolution, have kept the tradition alive and passed it along to the next generation. Mitra Sumara is not an old-school Iranian combo, but a 13-month-old New York outfit that adds its own roughed-up take to ’60s and ’70s Iranian pop. Led by singer Yvette Perez, a half-Iranian performer whose musical background—like much of her band—is in avant-jazz circles, Mitra Sumara adds some discordant touches to the source material, yet maintains a uniquely Iranian blend of melody, danceable rock, and R&B-influenced rhythms.

Mitra Sumara performs at 6 p.m. at the Kennedy Center’s Millennium Stage, 2700 F St. NW. Free. (202) 467-4600. The ensemble also performs at 10 p.m. at Tropicalia, 2001 14th St. NW. Free. (202) 629-4535.
