I want to put in a good word for this Bowie in particular; the show as a whole just smokes at both ends, but this Bowie is great stuff from the just pre-Type II days. The Vibration of Life is great in and of itself, but the central jam dives into cubist territory almost right off the bat, the angularity approaching the realms of the cartoonish right away. Upbeat but also sharp and right-angled, comparable in certain ways to a Mothers of Invention improv right around the time Lowell George was in there. For a second or two even Carl Stalling comes to mind. The cartoonishness pops up again later in the more typical E minor jam before they bring the song back around. Too brief (August is just months away though).
