解码器 Decoder (1984)

　　Hamburg, 1983. F.M. is a youngster leading an idle urban life, totally alienated from his environment, and only active when making “sound experiments” in his home studio. Christiana, his girlfriend, works in a peepshow...展开 on Reeperbahn. A chronically depressed customer is infatuated by her and tries to get more closely acquainted. The relationship between F.M. and Christiana is cool and distant, except for the moments at breakfast, when they share the muddled visions of their dreams.
　　One day F.M. suddenly wakes up to the surrounding reality, as he notices how the inconspicuous background music at a hamburger joint may have some connection with the junk food. It dawns on him that muzak is designed to control and brainwash the masses, not unlike lobotomy. On top of its paralysing effects, muzak is also laced with subliminal messages. F.M. decides to go back to the bar and records the muzak for his own purposes. He starts to develop a form of “anti-muzak” in his studio, by playing the original material backwards, or at a wrong speed, or by mixing it with interfering factors like sounds of street riots or squealing frogs.
