3 guys (Evan Stephen, Tiborg, and Lanolin Sparks) explain sound in "The Noises Rest" which was for a PopRally event Silent but Deadly: An Evening of Comedy Shorts, January 6, 2009 at MoMA.
Quote from the video by Lanolin:
I see that at the center of the beauty of film is a richer center, which is the beauty of sound -- and the center of sound is really silence.
