Jazz from 1957 to 1967 was the most definitive.

Newbee, thanks for the help. I heard Miles mention "Modal jazz" way back then, and I didn't know what he was talking about and I still don't.
Right now, I am hoping someone can "hip me" to the best "West Coast Jazz" available on CD. I also saw a silly comedy movie on TV, set back in the 40's I guess, where they had "Blue Grass" that sounded good to me. If someone has seen that same silly movie, maybe they know what the music was.

Foster_9, could you clue me in on your favorites by Miles after "Bitches Brew"?

Unfortunately for me, this thresd is too true; I am having a hard time finding new music.

Hi Orpheus10, I missed your question from several days ago.
After Bitches Brew things got very spotty for me regarding Miles' music. Over the years I have listened to and enjoyed the double live album "Agharta," "The Man With the Horn," "Tutu," and"Amandla." One I have that was given to me that I really don't like at all is "Live Evil."

Foster_9, thanks for the tip, I realy appreciate you cluing me in on some new music. I have the same opinion of "Live Evil".
