Sun.Barbez, a New York-based cabaret-punk ensemble, mixes covers of Bertolt Brecht, Erik Satie and Black Sabbath songs with arty folk-rock originals at DC9 (202-483-5000). . . . Formed five years ago by a sextet of Tehran art students, Iranian rockers 127 mix American and British pop and rock with jazz and Iranian folk influences. Its journey hasn't been easy: Western music was outlawed in Iran after the revolution of 1979, and the group was denied permission to release records or play outside Tehran's university, performing publicly only five times in its first four years.

The band arrives at the Black Cat (202-667-7960) with the Cassettes, though you might want to call first to confirm.
