"Karajan's m9 sounds too much like............hmmmmm......., Karajan"
Yeah, but see; the reason I like his M9 so much, is that it DOESN'T sound like the usual Karajan, such as when he's doing Bruckner, for example (I do like his VPO B8). Let me explain: Karajan used to say that every piece of music has only one true climax. But he didn't conduct his Bruckner that way. For the most part, it was just a series of huge, overriding climaxes - one after another. Karajan conducted Bruckner with the same sort of enthusiasm that Bernstein nearly always applied to Mahler. But Karajan's Mahler 9 isn't like that. The third climax is, indeed, THE main climax of the first movement. And Karajan truly nails the climax of the fourth movement Adagio, which many people fail to do. He succeeded in making the two big climaxes in the two outer movements, truly the major climaxes of the work (and actually, the first movement climax is an "anti"-climax). As a result, it gives the work - as Todd mentioned - an overriding sense of line. Anyway, I like it.
