It is quite amazing. Imagine Syd Barrett's Pink Floyd as a collection of jazz musicians and African drummers, playing at their best and - then you start to get the idea. Other Planes of There from 1964 is every bit as strange but not as effective. The music was in danger of becoming totally abstract. It's not my favorite period - to me the music is difficult to enjoy.
Some people really like it, though.
To me this type of music is sociologically interesting, to see the jazz tradition subverted into expressions of such anger or whatever you care to see it as, but I can't get into it as music. It's on a great 2-fer with Fate In A Pleasant Mood . Ra and the Arkestra continued in this direction. I don't really like them. Larry Young style of soul-jazz organ playing.
