You know, I had a similar experience with Hadi's playing on that disc as you did describe so eloquently. I had the a real bad old remaster (from our good friends ZYX in germany), and never liked it, sounded so bad. Then I got the Avenue edition and it blew me away! Actually, Hadi's playing blew me away... On the earlier stuff with Mingus he's got his sound together (as on, say, "Blue Cee" from The Clown), but on this one he's really really good.
