"You can tell the history of jazz in four words. Louis Armstrong. Charlie Parker." - Miles Davis
One of the few filmed s a one-hour movie, Improvisation (1950), by Norman Granz (founder of Verve Records and its subsidiary Clef among other labels associated with Parker), which opens with two songs featuring Charlie Parker:
"In the opening number in the first sequence I have Coleman Hawkins and Charlie Parker playing I think for the first time together and sharing the same song... And it's interesting to see how pleased Charlie was to be playing with Hawk... because he even lifted his chair from its original place, carried it over so he could hear Hawk do his thing. When Buddy Rich did a break Bird was interested in that and you could see him laughing as he enjoyed it."
The title, "Improvisation," refers to "what jazz is all about," in Granz's words.
