Charlie Parker wrote that tune over "changes" of an older tune (I have no idea) to "scare away" the "amateurs" from getting on the bandstand. It was a whole "thing" called Be-bop. Cab Calloway, a band-leader of the time, called it "Chinese music". It was an intellectual masturbation process that jazz went thru. So these many many many (many) years later, it's still a "standard" to show your chops. Wowie Zowie.
But I listened to it. I wish the camera was on her for the whole "head" of the tune, it is one acrobatic romp. I am of a certain age where that guy with the de-fretted Fender was rouging around & I was at Berklee and I had a Real Book. I tried. My chops were never THAT good. The tune has interesting chord changes and turn-arounds. It's a good study.
At that precise time I was venturing into "other musics", and having a hard time with the educators @ Berklee so I left, formed a band with other Berklee Outcasts (now that would be a good name for a band), and got a job as a dishwasher, which eventually brought me to food preparation skills of the caliber to run a successful restaurant with my name on it.
But never any $$$$$ doing the music I love.
So it was cool to listen to. Once. Made me think, Maybe I should check one of those Kala basses out. It's nice and small and my back might not hurt when I play it sitting down and it's a lot smaller than the Stick...
Then I picked the Stick up. Mumbled along on Donna Lee, and said, "Hey this stick is pretty cool. F*ck the pain..."
