"Wherever we are, what we hear is mostly noise. When we ignore it, it disturbs us. When we listen to it, we find it fascinating. The sound of a truck at 50 m.p.h. Static between the stations. Rain. We want to capture and control these sounds, to use them, not as sound effects, but as musical instruments. […] Given four film phonographs, we can compose and perform a quartet for explosive motor, wind, heart beat, and landslide."
— John Cage, “The Future of Music,” 1958 (via floatingheart)
