John,
The M3 that I attended was very good except for one thing. What I didn't care for - which nobody who knows the part would care for - is that they played the entire tambourine part on a military side drum; what most drummers would call a tom-tom. This not only effects the end of the scherzo - where I thought it truly sounded bad - but almost the entire development section of the first movement. There are also a few tambourine rolls in the second movement as well. For the life of me, I can not imagine how any percussionist could assume that Mahler meant a drum instead of a tambourine. Maybe it was Mr. Schwartz's idea. But beyond that, it was a very good M3 indeed. Hopefully, they won't repeat doing that.
