John Cage's 4'33". The pianist walks up to the piano, sits down, opens the keyboard cover, waits 4minutes and 33 seconds, closes the keyboard ccover, and gets up and walks away. Silence is one a part of the musical material a composer uses. John just took this to the extreme.

Little Black Egg, by the Nightcrawlers; I still have not figured out what the hell it means, let alone why the song exists in the first place. If anyone knows the history of this song I would be very appreciative.
