The compelling documentary How to Get Out of the Cage (2012) by award-winning filmmaker Frank Scheffer presents an intimate portrait of John Cage (1912-1992), one of 20th century's most important composers. From 1982 to 1992, Scheffer worked with Cage on numerous occasions, which resulted in unique archives of historical audio-visual material, including interviews, musical performances, and images of locations related to the composer's life and work. In all Scheffer's works related to Cage, he used the old Chinese method of chance operations based on the Yi Jing - as often used by Cage himself in his compositions. Instead of using chance operations, Scheffer edited the film in the usual way that is based on choice.
