I'll stick with the Resurrection, and the 3rd, which I had the privilege of singing.
Lots of emotion, but not enough to freak me out..............just make me cry. Both of those finales bring you to an emotional peak and just when you think you're going to break, Mahler brings you even higher. You have to start out with a lot of emotional reserve before you listen to either of them!
Strauss isn't nearly so bad, but the Nietzsche thing bothers me a bit.
