Frogman, without a doubt that's my favorite album cover. I'm sure it was taken during the best time in Miles life, he was "insanely" in love with the woman on the cover.
That was when Miles was going into an "angular" approach to his music; this would be reflected in "Bitches Brew". In general, I preferred the flowing music him and Gil Evans produced.
