I first heard him back in the very early 1960s and was taken by what we then called "electronic music", much of which predated/led the way for some rock and roll forms that followed. The older people around us called it noise. We called it "Gee, I wonder what we should call that?" It opened areas of, as you said, Gargoyle, music. Made it the domain of all things, not an elite. He seemed to bridge areas of music where there WERE no areas. Sorry to hear of his death. Thanks for posting.
