"Expanded cinema" encompasses film, video, performance, and multiple-projection. While video in museums has received considerable attention, experiments beyond the exhibition space have not. Here, leading scholars trace expanded and multi-screen cinema from its origins in early abstract film and the Bauhaus era to postwar happenings and live events in Europe and the United States, the first multimedia experiments of the 1960s, and the fusion of multi-screen art with sonic art and music from the 1970s onward.
