Among a handful of Russian conductors I have a soft spot for Svetlanov when it comes to Mahler.
He seemed to feel at home with Mahler's myriad instructions, especially regarding tempos and tempo relations; he almost always found an efficient way to realize them on the podium.
Mahler Ninth was one of his fortes with interesting and convincing arguments held in check, not the least of which is the great Andante Comodo (opening) movement. It flows, sings and unfolds naturally but it also moves along in a tight structure, leaving nothing in vague gestures. In Svetlanov's hands the Rondo Burleske (III) becomes a nail biter racing blazingly in just over 12 min. The Finale, again, just flows with little sentimental extremism a la Bernstein. But it works beautifully as it does in I. Not that it lacks power and overarching emotions. They are all there, unmistakably!
A top notch Mahler Ninth and a very important historical archive.
