1) Copland: The Smits/SONY set seems the most likely candidate,- the sound seems okaaay,- is there anyone who has the kind of recorded sound that might transport these "ugly" pieces? (of course, only those 2-3)
2) 'Concord': a toss up between Aimard and Hamelin (Hyperion or NewWorld?-

). I seemed to like Hamelin's NewWorld sample better than Aimard's, and that seemed to be totally at the hands of the engineers: the NewWorld has their typically sumptuous and close-mic'd sound, and the Warners had a more "cold and clinical" sound (which may not be sooo bad).
Also, where is the original issue of Aimard's '3 Quarter-Tone Pieces' with Lubimov?
