Good comment about the tuba!
All of those "things that go bump in the night" sound effects--the offstage chimes, plucked harp, icy-toned low celesta, and solo tuba--are perfectly in place. Indeed, I have to single out the tuba player for special praise. Eschenbach pays a lot of very welcome attention to Mahler's bass lines, and much of the credit for their pliancy and vividness goes to the tuba.
How often do we get noticed like that?
Is it Carol Janisch, or a predecessor on this new recording?
I think either way, I will have to listen to this one (particularly as I am practicing Mahler 6 for concert myself at present)!
