Oh my goodness, yes! Yay! A compatriot. This is good, very good indeed.
John Cage is interesting in that he explored the idea of letting go of the controls a bit, loosening up, and that scared and excited people in all kinds of ways. I can't possibly give you an overview of his work - from what I've read, his oeuvre is so subtantial and varied that one really has to just take each piece on its own terms. I do know that he did exciting things, though - things like setting up a bunch of microphones listening to sounds like old records and the street outside the performance space, and having dancers glide and pirouette through a maze of light beams, each of which activated a different microphone when interrupted. Surely an artist worth listening to. 🙂
