Well, there IS a technicality that allows discussion of "Das Lied" here, since there is a chamber version in existence with PIANO and HARMONIUM assisting strings and winds. Pretty neat, all in all.
Yeah, I adore this piece. Also, the final Tenth, completed by Deryk Cooke. But there's not one damn piano in it, so forget I mentioned it.
You know, I don't think that's the version that the OP had in mind. And too, my point wasn't that it shouldn't be discussed, but simply that the polite thing to do here is to put an "OT" at the beginning of the subject line when wanting to discuss something not really related to the piano.
I was in a particularly cranky mood when I posted, I guess - I'm sorry about that.
I might add that while I used to adore Mahler, that adoration has turned into mere respect these days. All that hyper-emotional stuff has gotten old, and seems a bit cartoonish and kitschy to me now. It also feels manipulative in a way I don't much care for, even if it's highly effective - it's like Spielberg movies that way.
