You're right, jazz was perfectly formed from note one, each practitioner an astute student of music as a whole, and each having been a graduate of various institutions of higher learning.....
Doubtful. Less doubtful is that the genre evolved from folks who were struggling to make sense of the influx of influence that they found themselves then surrounded with. A type of punk classical (as it were/if you will) with the innate information of generations of polyrhythm coursing through the practitioners DNA. Doesn't make it right or wrong, but the notion of a perfect school of music forming instantly is, to my knowledge, not a part of the history books.... If you know otherwise then please enlighten us all.
Didn't listen to that recording btw, heard all that stuff as a child. But kudos on the referencing.
Now, back to our man Ornette....
