"I spent my first week in New York looking for Bird and Dizzy. Juilliard was only a smokescreen, a stopover, a pretense I used to put me close to being around Bird and Diz."
Those were Miles very own words; Diz didn't go to St. Louis looking for Miles, he came to New York looking for Bird and Diz; that was from the start, which tells a lot.
Dizzy G, was the ultimate "jazz musician" who could innovate like nobody you ever heard; that's how he was able to consistently play "jazz" that sounded fresh and brand new from the 40's until his death. He never sounded "stereotypical", meaning clinging to certain riffs that he repeated, but each time he reworked his old tunes until they sounded new.
While Diz never left the "jazz compound" he pushed and re-invented his music in such a way that it was always new and fresh.
Throughout most of my "jazz life" I was equally a Diz and Miles fan; that is until Miles trolley jumped the tracks, and I no longer liked his music. Trying to quantify Miles new music would give me a a "brain-ache", therefore I won't, but leave it at the fact I could live without it.
Enjoy the music.
