"Mingus Minus Mingus", didn't think about it, but that's exactly what this was. His music can be played and heard on a deeper level; I know that sounds trite, but there is nothing shallow about Mingus's music. On the second clip, he was just as much into anthropology, as he was music; that would be brooding.
Mingus was a deep and heavy thinker who expressed his thoughts. "Can you imagine him and Miles stuck in a car from New York to LA, with Mingus rapping, and Miles unable to put two sentences together before giving out".
Enjoy the music.
