Crap! You're right. Yeah, I noticed a bunch of other noteworthy names on that list, too. Going to take some time working on 12 bar blues improvisation tonight... honestly haven't played around with that stuff for 12+ years at this point... super rusty and humbling to struggle even with basic improv because I'm so inexperienced with this. 7th chords and 9ths/11ths/13ths and inversions, cool! Scales, cool! Now put them together and play both hands and wing it. Fffffffuuuuu
Makes me laugh that I was jazz soloing back when I knew no theory but now I am filled with trepidation and self-doubt before improv. I am a clown
