The third documentary for Documentary Month here at the Monday YouTube Fix is titled "1959 The Year that Changed Jazz". It is a fascinating look at that seismic year in jazz history that featured the release of four legendary recordings:
Miles Davis "Kind of Blue"
Dave Brubeck "Time Out"
Charles Mingus "Ah Um"
Ornette Coleman "The Shape of Jazz to Come"
This film is filled with nuggets like the fact that Miles Davis' "Kind of Blue" was recorded in just 7 hours and that all but one of the tracks was the very first take! This is a fantastic documentary on some of the most important music ever recorded.
