San Francisco transplants probably already know who Space Lady is. This mysterious street performer and outsider artist, with the earthly moniker of Susan Dietrich, used to float around playing her thrift store Casio keyboard (with a winged steel helmet on her head) while singing haunting and childlike interpretations of pop songs—most famously David Bowie’s “Space Oddity.” Her otherworldly voice, paired with retro synthesizer beats, mesmerized thousands. She’s reemerging (from outer space?) at Magma Fest after 14-some years of silence, so don’t miss this opportunity to bear witness to this bizarrely beautiful cosmic crooner. With Geneva Jacuzzi, Goddess Kring, and SciFiSol. (Chop Suey, 1325 E Madison St, hollowearthradio.org/magma, 8 pm, $8–$15 sliding scale, 21+)
