In 1972, Robert Morris and Lynda Benglis agreed to exchange videos in order to develop a dialogue between each other’s work. Morris’s video, Exchange, is a part of that process—a response to Benglis’s Mumble. At the beginning of the piece, Morris comments on the nature of the collaboration, their interaction, and what they represent to each other. Morris’s speculations about work, travel, and relationships are juxtaposed with frozen images of race cars, Benglis herself, images from Benglis's video, and Manet’s Olympia.
