The Revenge of the Dead Indians
The Revenge of the Dead Indians (original German title: Die Rache der toten Indianer) is a 1993 documentary film essay directed by Henning Lohner about composer John Cage and his theories about music. It pays tribute to Cage's thoughts, music, and influence and has been described as "an unexpected and fascinating combination of intellectual thought, viewpoints and opinions." Featuring discussions with Cage himself as well as interviews with friends, companions and colleagues of the famous composer, the film thematically combines "found" video and audio landscapes inspired by Cage's texts, music and philosophy.
