I got my Zinman M9 last Tuesday (the seventh) and meant to do a review but never got around to it. I will at some point though.
The ending of the Rondo is a real sticking point for me. The tempo is no different (perhaps a hair faster, but I really do not think so) at the end than in the beginning, which, judging by every other recording I have heard, is not the way it is supposed to be done. The first movement is so vast that I need more time with it before I can report my thoughts. I did think that the second movement lacked that final degree of harshness, just as did the Rondo. Zinman's "gentler" sound pays off at times in the Finale, but I have issues there too. The most noticeable, for me at least, is his sudden accellerando at 6:27 (during the C sharp minor violin solo). The viola solo is nice and controled, but for some reason when the violin solo appears Zinman speeds up. For me that is a passage of great emotion and thus it is not to be rushed through. Playing the whole passage at a quicker tempo is one thing, but speeding up halfway through...no thanks. It just rouins the mood. If one wants to speed up the tempo, one should do so at the french horn solo just after that passage--it is a nice, natural transition from a quiet, minor theme to a louder, major one. For an example of how well this can be achieved, Bernstein does this wonderfully in his Berlin recording.
Overall...I am a bit disappointed with this recording, as I had much higher expectations for it. But I am glad I have heard it because, like probably many others, I would not have been happy until I had. I look forward to hearing it on an SACD player if I can ever find one to listen on.
So, my "favorites" list remains pretty much unchanged: Rattle/BPO, Bernstein/BPO, and the Barbirolli/BPO is growing on me--I have always liked his first movement. Runners up: Levine/PO, Giulini (especially for his first two movements), and the Bernstein/RCOA (even with that dischordant wrong note there in the Finale).
