For a piece I am not crazy about (Ravel's Sheherezade is more my cuppa) I have ended up with five recordings. Not sure how that happened. I have three recordings that I am really fond of - two Celis (one EMI one DG) as well as the Kondrashin (all of which we have in common along with Karajan and Reiner). Will check out your other recommendations as you never know which conductor is going to totally open up a piece for you.
ps have been wallowing in the Orfeo release of the Hans Knappertsbuch, Günther Treptow, Helena Braun Tristan. It's completely overpowering. About half way through I was momentarily thinking that maybe I would never listen to anything else!
