>> Most prog-rock seems to me to be the band sort of "incohesive aimless noodling around for a while". You made a point. Certainly one of the most common complaints about prog rock. Interesting you mention African-American since King Crimson, one the granddads of prog is influenced by African-American music... which is jazz. Not blues though, like most rock bands in the 60s e.g Cream. One of their nature is to write compositions that involves odd time signatures (not easy to hum to) and weird rythmical patters that doesn't feel natural, at least to average music listeners. Indeed very experimental. If you are into that stuff, probably you'll like Sun Ra. He's more difficult to grok, though.
