Worth checking out: there's a free screening of Theremin: An Electronic Odyssey on Sunday, 6pm at Utility Gallery (5224 Blowers). It's a 1993 documentary film about the life of Leon Theremin and his invention, the theremin, featuring monologues by Robert Moog and Brian Wilson, among others. Apparently Theremin was kidnapped by the KGB in 1938 to work on electronic projects. Crazy story, crazy instrument.
A few years ago I saw Brooklyn theremin-duo One Ring Zero at the Khyber Club, accompanied by friend, author Jonathan Lethem. But they're probably best known in literary geek circles for their Toronto performance with Margaret Atwood.
