Watched it all.... LSD is a great drug huh?
A lot to take in there once you get into it. Not sure how to process it really but if that was back in 73 then so much of it sounds familiar with what new sounds we can create digitally these days and they did it with drums, sax's and voice. There is also a kind of tribal, trance like feel to it.
And I'm a fan of the broken drum beats too, a quick search says that that probably started with him.
Now I have watched it'll probably come up in the youtube suggestions so I'd probably watch more over time.
