Marty, as one Mingus nut to another, I agree entirely with your post above!
I've been CHAMPIONING "East Coasting" for a long time. A truly special recording. And I see "Stormy Weather" trumpeted around a lot, hardly underappreciated. (Deservingly so, but I still like the Hadi-Knepper-Shaw band material a hair more for the denser front line and for the piano. . . . Me likey a piano with Mingus).
