575 Castro St. reveals the play of light and shadow upon the walls of the Castro Camera Store set for the Gus Van Sant film Milk. These mundane shots are almost bereft of movement and sound. All the better to showcase the range of emotions evoked by Harvey Milk’s words on the soundtrack. The audio track is an edited version of the 13-minute cassette he recorded in the store on November 18, 1977. Labeled simply “In-Case”, the tape was to be played "in the event of my death by assassination".
