Very good set. Now out of print (very quickly went from released to out of print, the estate dropped its deal with Concord). . . not easy to find.
Quickly? blick of a freaking eye!
I missed it originally, too, but I just found a copy for $60 (including tax and shipping) on J&R! They claim it's in stock (still), so if you missed it and are kicking yourself...
And it's darn great! I gave it a listen now, almost finished it in one sitting, couldn't stop (only sleep made me, somewhere into the fifth disc, past 3 a.m.)
