October 5, 2009. Performance and video pioneer Joan Jonas screens and discusses her outdoor performance pieces Jones Beach Piece, Nova Scotia Beach Piece, and Delay, Delay that she developed into a video piece titled Song Delay (1973). First performed in lower Manhattan in 1972, the footage was shot from the roof of a loft building. From there, the audience overlooked the performance taking place in empty lots below with a view to the distant docks of the Lower West Side. Performing with a cast that included Gordon Matta-Clark, Jonas choreographed a theater of space, movement and sound with the urban landscape of New York in a featured role. She performed this piece a second time in Rome, where the audience watched the performance from the other side of the Tiber riverbank. Joan Jonas is a professor in the MIT Visual Arts Program, teaching performance and related media.
