Class Actress is becoming a class act — and you can catch it at Crosstown tonight

Elizabeth Harper’s story is so damn Brooklyn that it’s almost cliché. After releasing an album of acoustic coffeehouse songs under her own name, she hooked up with two producers, Scott Rosenthal and Mark Richardson, in the hip New York borough, and they deftly swept her singer-songwriter sound into electronic territory. The result: Class Actress, a steadfastly vintage-sounding unit, like a crate-digging souvenir from 1986.
