o10, I was quite surprised to read this from you: "Here’s Miles Davis sounding like Cannonball wants him to sound".
With your deep experience with jazz personalities do you really feel Miles’ ego by the late ’50s would allow him to play as someone else wanted? I just can’t imagine that happening, even as a sideman on someone else’s recording, as commonly credited in this case. His approach on that recording sounds pretty much like the other things he was doing at that time. And given how ofter Miles changed his style, just as frog mentioned, can you compare anything he did in 1957 to that from 1964?
BTW, I never owned a Marantz CD player but I’ve heard models a few friends own, good choice.
