We know Mahler had early fans like Walter, Klemperer and so on; As well as early obsessives in what was the postwar recording capital, such as Horenstein and Barbirolli. But as far as those to come along a split second later; In other words, those to lay out complete symphony cycles and launch him into what has become a less sketchy discography, we have primarily Kubelik, Bernstein, and Haitink. I automatically dismissed Haitink, for most would agree him more a professional conductor than a student of any chief musical particulars, though that can't be said for neither Kubelik nor Bernstein. I've heard some say that the DG Kubelik boxset would have to be torn from their stiff, cold, dead fingers and that he had the best sense for Mahlerian counterpoint. While Bernstein is probably the most celebrated Mahlerite of all time. But who trumps who, or where do you see their stature headed in the forseeable future?
