elizabeth,
IMO, Mahler really didn't become a prominent composer (other than live performances) until stereo came into being. Mahler's orchestration demands the capability to listen in "stereo," permitting the listener to hear the depth and distinctions among the instruments. Also, IMO, stereo permits a better dynamic range of recordings. (My favorite is the 2nd, with Bernstein)
