My best friends brother wanted to become a concert pianist, so his parents bought a baby grand piano. Hobart practiced diligently, and every time he practiced, the next door neighbor would come over and watch him in mesmerized awe. After Hobart finished, the neighbor would sit down and repeat him note for note; that was amazing beyond belief.
Hobart went to Juilliard, got his degree in music and became a teacher. The next door neighbor became a jazz musician and was a star in St. Louis. The cat could jam, and I went to most of his performances over the years he played, until substance abuse cut him down.
I never heard Hobart play, and my friend, his brother said he was into classical and taught music but didn't perform. Over the years Hobart lived an affluent life style; skiing, vacationing in Europe, bought a boat and retired in Florida after he left New York where he taught music.
Although being a "jazz musician" never came up in Hobart's life, the fact that he never performed tells me he couldn't have been a jazz musician even if he wanted to. I said all of this to say that as fans we don't seem to realize how special a good jazz musician is; they're born, not made. No amount of study or practice will enable a person to improvise at the level of a good jazz musician, and no matter how financially successful some other musicians are, a jazz musician knows within himself that he can do something very few people can do, and no way can they learn how to do it. Financial success does not equate to being a good jazz musician and being able to rapidly improvise good sounding music; "either you got it or you don't".
Enjoy the music.
