@jafant Thanks for the suggestions. I have just about every OG Blue Note produced. So, i am familiar with these folks works.
My OP was wondering more along the lines if the particular genre at the time...mostly Bop, was pretty much a ’blowing session’ for a lot of these musicians. Which would lead me to my next question, perhaps this is why Miles Davis ’progressed’ into the discovery ( if you can call it that?) of fusion. Maybe ( and I don’t know this as a fact) he felt that these ’blowing sessions’ were somewhat limited in their scope and wanted to move the genre of jazz forward. This would be my guess, maybe someone knows more definitively about this theory??
