Got to listening to this on a recent road trip. I hadn't heard it much, but this is a superior set that gives you a great idea of Mingus as an artist.

My favorite part is that you can hear him talking throughout. You can't always make out what he's saying, but you gather he's giving instructions and encouragement (maybe admonishments, too) to his band, and in places you hear him singing and humming along with the music. For me, it's great because shows how in control he was of the vision being put in front of his audience. It's Mingus' world. We just live here.
