I've been doing some comparison listening recently... (and am reviving this thread as the most appropriate place for comparisons, despite the "modern" adjective in the title)
Fischer/Budapest Festival. What a disappointment. The main problem is in the first two movements, where the violins have a softness and lack of focus which is starkly different from the sound of the rest of the orchestra. At times they seem to be in a different acoustic - as if half the violinists are seated behind the winds and brass in the far back left of the stage. Their soft, caressing phrasing just isn't tragic, and the flowing violin melody of the slow movement, particularly, is deliberately stutter-stepped in an effort to de-romanticize it and reduce momentum. The final two movements are much better, but damage is done.
Harnoncourt/Berlin. To my surprise, Harnoncourt noodles around a bit with melodies too, introducing a bizarre rhythmic halt in the tune that's introduced by cellos/horns in the first movement around 1:30-1:45 (and then 8:40). I guess to make it waltzy? But he doesn't divide the Berlin Philharmonic against itself. Like the Budapest recording, the woodwinds are quite prominent (love the horns popping in at 9:25), but unlike the Budapest recording, this transparency doesn't diminish the momentum of the outer movements. I wish the first movement's final chord didn't taper off, but man, the timpani sound perfectly doom-ish. The rest of the symphony goes well, and the finale really builds nicely. Much better, but not quite A-list.
Kertesz/Vienna. At last, a big rich full orchestral sound and no mannerisms! The first movement is absolutely stunning, as hair-raisingly apocalyptic as Kleiber (love the abrupt cut-off of the last chord, rather than letting it fizzle like Harnoncourt). The slow movement glows, the finale glowers. Maybe, maybe, there isn't quite the transparency of the others, but there is passion and force and emotion and all the things I really want to hear. I've got a few others I want to re-audition - an American circuit of Janowski/Pittsburgh, Levine/Chicago, and Dohnanyi/Cleveland - but will leave things contentedly here for today.
