Dissonent Plane, an experimental music store in Seattle, is partenering with Davidson Galleries to present an SMS listening party.  SMS is a "series of six portfolios of multiples released in 1968 by the surrealist William Copley" and "six of the works in the SMS portfolios are sound pieces", including a phonograph record by Marcel Duchamp.  The party will be tonight at 7 pm and will last three hours.
