A final edit: Why the hate for Cage, by the way?
Cage was criticized for focusing in sound rather than in music. Cage didn't want to make sounds something psychological, evocative or harmonic, just sounds. see
Ok, the concept is logically flawed. Sounds really needed Cage to happen?
I hate when these artists try to justify their concepts with bad philosophy and fail in execution as consequence.
I'll keep with the good ol' Beethoven instead:"Music is a higher revelation than all wisdom and philosophy, it is the wine of a new procreation, and I am Bacchus who presses out this glorious wine for men and makes them drunk with the spirit.'"
Edit: Also, hearing Cage talking about his music or hearing others talking about Cage's music is far more interesting than actually hearing Cage's music, that's not good.
