Listening to the crap Cecil plays over KD's composition and solos, I bet KD wished he hadn't shown up either.
I think the producer (Tom Wilson?) wanted to present Cecil in a more mainstream context, and hired the players. Of course, Cecil was having none of it, and the session just doesn't jell. Cecil and the others seem to be having a tug of war, and nobody wins. To further complicate matters, the session has since been issued as a Coltrane-led date, which makes Cecil the odd man out, even though it was originally his date! A noble experiment that failed.
An experiment - I'm not sure how noble it was. One thing's for sure - Cecil will play his music, his way, without concern for whatever "concepts" record producers may have.
