Wow, I would love to hear that Previn M9 someday.
I'm looking forward to receiving the Ozawa/BSO/Phillips M9 I just ordered, I hear so many great comments about the playing. Because Ozawa's SKO M9 sounds underrehearsed, it sounds rather raw, but it sure is exciting to listen to! Another memorable underrehearsed M9 is the Horenstein/ONF/Disques Montainge M9, which has it's moments too, though it can't really compare with his LSO recordings...still on some days I really like it.
I was thinking that Kobayashi's conception for the M9 would be better played by the BSO or VPO, and CPO...same with Inoue (though his recordng is indeed well played through and through).
As for Karajan, I still really like his M9 and should have included it on my list. I have a live broadcast of a Karajan M9 that I haven't listened to yet, but I hear it is much better than his officially released recordings?
I wonder if that Maazel DVD is hard to find, sounds like a good M9 as well.
