Mind-boggling is what it is. The fact that this masterpiece by Mingus hasn't yet been reviewed (or that the reviews have been erased and not begun again). Also that this album isn't his bestselling release--that this album isn't one of the bestselling releases of all time by any composer musician artist genius. Perhaps that isn't exactly mind-boggling, given the general tastes of the music-downloading masses. But it should be mind-boggling, given the unbelievable genius displayed in this work.
Listen. Mingus is, still is, even now, well after his physical existence on this earth ended, one of the greatest composers we've had, and as far as I can tell, this is the greatest thing he ever composed, and he composed a lot of great music. I won't describe it, because I can't and because it couldn't possibly do justice to this work of art. Just listen to it. If you're afraid of committing the 10 bucks to something you might not like or listen to often, go get if from your public library, if they have it. That's how I first heard this.
Whatever you do, go listen.
