I transitioned from Beatles-to-Henrix-to-Zappa with random but meaningful bumpings into Soul (which was a whole other story...)
It was a window in time...jazz-rock was about to become fusion (but had not yet), the big bands were still going (on all guides), the avant-garde was rapidly evolving. Europe was teeming with Americans and natives clicking decoratively and together, and most importantly...so many major voices were still alive, gigging, and recording. And the reissues were just beginning to get rolling!
I like to use Wayne Shorter to illustrate - just about a year in. I knew of Wayne from records by Blakey, Miles, and Weather Report. I was too dumb to realize that it was not basically all the same person.
Silly me.
