In 1952, American experimental composer John Cage composed what he considered to be his most important work, 4'33" ("four minutes, thirty-three seconds") which is basically about 4 minutes of silence in 3 movements (Cage's idea is that the ambient sound becomes the music).
Fast forward to 2012, where Adam Lucas took it to the next level. Here's Nicolas Cage performing John Cage's 4'33." See if you recognize all of the movies used.
