Thanks for posting this, it was an interesting listen. The fact that every track exactly copied the improvisations rather than improvising around the tune (which I did not expect) says something about the merit of the photographer's argument, though. Although it doesn't say any more about it than the fact that the compiler got permission from everyone beforehand.

It's a separate work from Kind of Blue only to the extent that a different mix or running the tracks through a distortion pedal would be.
