It's really quite unfortunate that most of the users of this forum cannot appreciate the work of John Cage. Not only is he one of the most important composers of the twentieth century, but he is one of the most influential composers in terms of notation. I challenge any user to find a composer who came after Cage who was not influenced in some way by his work, and moreover, find any piece making use of graphic notation where Cage doesn't pop his head out. 4'33" not only changed the face of music, as it introduced silence as one of the major components of any piece of music (and validating that space between movements in any work of music, from Bach to Shostakovich) and the use of rests in general, but we can thank Cage for changing the way we all look at art, whether or not some of us choose to acknowledge so.
