In 1989 John Cage started working on a commissioned project for the Museum of Contemporary Art, Los Angeles (MOCA) – a chance-derived, four-movement composition for museum entitled Rolywholyover A Circus. This was a long-term performative, multicentred event for gallery installers, audiences, artworks, artifacts, scores, plants, stones, books, chess tables, chairs, and pieces of ephemera. According to Julie Lazar, the MOCA curator who worked with Cage on this project, while doing trials and preparations for Rolywholyover the artist composed two other compositions for museum. Both of these other works were smaller in scale: Changing Installation (1991) for the Mattress Factory in Pittsburgh and museumcircle (1991) for the Bayerische Staatsgemäldesammlungen, Neue Pinakothek in Munich.
