I am listening to the Finale from the Schwarz/RLPO M9...I have to admit, I really like this. I like his dynamic contrasts, even if he does do some stuff I have never heard before. The string playing is similar (to me, anyway) to that from Rattle's Berlin recording but is different in some areas: for example, the strings are more expressive. I think passion takes priority over execution here, but passion is the order of the day and there are no glairing errors that I can hear.
I have also listened to the other movements, just not in as great of detail. I can say though that Schwarz brings out some interesting ideas with his shaping of the phrases etc. The Rondo is deliciously fast, so Scott you should like this one. I have not spent as much time with the first movement, but what I have heard I have liked.
