Happy spring! I keep saying to myself I'm going to post Moondog, so here he is - an American original with a one-of-a-kind musical story, which you can read here.
Keep searching YouTube. You will find lots. Albums I have that are outstanding include Sax Pax for a Sax, A New Sound of an Old Instrument, and Rare Material - all great stuff. Maybe it's minimalism, but I find it hard to pigeon-hole this guy into a single category. Check out this 1998 interview - excellent read.
