Going up

Audio producer and artist Yowei Shaw's project Really Good Elevator Music is an experiment replacing the usual Muzak with aural creations pumped into office buildings in the Chinatown North/Callowhill area through March 31. The idea is that the new sounds might stimulate social interaction (as in saying "What the heck is that?" instead of staring at the floor).

Among the 13 two-minute pieces, created in collaboration with six artists and musicians, are one in which an eighth-grade music class tries to a figure out a medley of Miley Cyrus songs for their graduation, and another in which participants in an audio production workshop at a homeless shelter talk about their favorite food. But you don't have to ride the elevators and hang out in a waiting room or lobby to hear the results. Shaw hosts a listening party at the Asian Arts Initiative, 1219 Vine St. Time: 6 p.m. Admission is free. Information: 215-557-0455 or reallygoodelevatormusic.com.
