I'll add my "Jr. Member" two cents for what it's worth: I like both the recently released Jurowski / LPO and also the Tennstedt / LPO live recordings. However, I do realize that Tennstedt is not everyone's cup of tea (nor even mine every day, or in every symphony).
I have the Fischer M2, and really want to like it more than I do. I can appreciate it is a fine recording and performance... and yet I find I don't reach for it very often when I want to hear the Second. Perhaps it will grow on me over time.
I guess I'm still looking for my "perfect" M2, but I guess that's part of the fun of being a Mahler junkie, right?
Cheers,
Herb
