Decoder (1984), by the one named Muscha, is the kind of film that should've been a wider known cult movie but isn't that easy to see unless you look to European DVDs and online. Set in a totalitarian cyberpunk metropolis where subliminal music used in a fast food franchise is subverted by anarchists to change the world, its a unique work that's stuck with me since viewing it in a fuzzy pictured form years ago. Its more of a mood piece than an elaborate narrative but its stayed with me for its colorful, dank atmosphere and how different from other sci-fi dystopia films it was.
Alongside a cameo by William S. Burroughs, the onscreen and musical contributions by the likes of Genesis P-Orridge of Throbbing Gristle and FM Einheit alongside bands like Einstürzende Neubauten is probably the most distinct aspect of Decoder. As of June 2015, the original soundtrack by these individuals and more is available on British and American iTunes, and I give you the following as a nice taster of its electronic hamper.
