Frogman, I am subjective to the Nth degree when it comes to selecting and listening to jazz music. If I detect 1 objective hair on my body, I will pull it out.
My musician friend who lived with me that Summer, never practiced (that Summer). What was an improvising, performing jazz musician going to practice? He didn't just start playing jazz yesterday.
Although I had been a fan of his eight years before he moved into my apartment, I had never heard the music he was currently playing. I was truly mesmerized at each performance, never the same music. We never talked music before or after the performance. He enjoyed telling me about his life as a professional jazz musician, and I enjoyed listening.
That was 40 years ago. When I reflect back to that time, I know there was something intensely personal between him and his "new" music. When he was on stage, he went to that place where jazz musicians go; that's where it's at, either you got it or you don't; he just let his fingers fly trusting his inner muse, there was nothing "objective" about that.
I recall that he played center stage at that big 4th of July extravaganza we have under the arch every year here in St. Louis, and got rave reviews. I didn't attend, I can't stand being in the midst of a bazillion people.
The only thing I've got to personally compare, is when I went out on the tennis court and hit perfect backhands and forehands. I wasn't thinking about anything, I just kept my eye on the ball. Of course I had spent years playing and practicing before this occurred, but it would not have occurred if I had been "objectively" conscious of what I was doing.
I witnessed on TV, the best game Isaih Thomas (Detroit Pistons) ever played in his life. When he got so tired that he barely got across the half court line, he threw the ball up, and nothing but net; he couldn't miss.
After the game news people were all over him; he said everything was like in slow motion and he was in what they call, the zone.
Here is where I'm coming from, if you're going to be a star jazz musician, you have got to quit thinking "objectively" about what you're doing; either you got it or you don't, but you can not get it by practicing (when you're a performing musician) That might be just the thing for a "classical" musician, but not an improvising jazz musician.
Of course if you're not performing, you have to practice; but an improvising jazz musicians performance has to be instantaneous; otherwise it sounds "stilted", and that's not good in jazz.
Enjoy the music.
