Rachmaninoff, Symphony No. 3 in A minor, Opus 44?
I had the privilege of hearing the Minnesota Orchestra perform this last evening. I know precious little about how to select an audiophile quality recording of this work. Can any of you classical buffs out there give me some suggestions? In advance...very much appreciated. Thanks.
