John Mehegan - Improvising Jazz Piano

The result Is that absolutely no one came to the famous jazz world out of these methods, in which analyzed how Art Tatum, Miles Davis, Errol Garner or Oscar Peterson played, just came up 'Maria Schneider' with her own way of reinventing Jazz.
Late musicians like 'Quincy Jones' had to go totally different from Jazz, and the Frenchman Claude Bolling was massacred by criticism for his works considered copies of what already existed in the past.
Unfortunately some people just wanted to make money, like the Boston school Berklee, such school that musicians have to hide that they studied there, otherwise they do not get a good job inside USA. They do today, what the Juilliard School abandoned decades ago, Berklee had only one worldwide explosion band, 'Spyro Gyra' and the artist 'Billy Joel' and a few other minor expressions.
By the way, John Mehegan methods are much better than any other.
