I seem to remember getting the whole NY Maazel cycle more for the orchestra, than Maazel. I love Phil Smith's trumpet playing, and Philip Myers horn playing...when he's "on." And of course, Stanley Drucker on clarinet and Joe Alessi as principal trombone. His Third stood out as having some pretty eerie oboe playing in that first movement that I thought was cool.
But that Ninth was just on the boundary of being too slow. It jelled, but was pretty massive. I look forward to trying it again. And I've seen that Bavarian one on Youtube...so I need to actually sit down and listen to that one, too.
I really didn't mind the Vienna one. There are certain little things he puts emphasis on...(or perhaps the engineers). And you're right, the M10 Adagio is superb.
