I haven't heard this recording, so won't I pre-judge it since there as SO MANY factors that go into making a successful recording. All I can share is that I saw/heard the Philharmonia in Berkeley over a couple of nights, and they're simply not for me in Austro/Germanic music. This is not the same Philharmonia as in the Walter Legge days, obviously. But they simply play in a manner that is too transparent for my liking, and with too little heft in the lower end of the orchestra (basses, tuba, etc.). The woodwinds are good, but certainly not as great as those in Amsterdam, Berlin, Dresden or Prague. They use a strange looking and, somewhat, strange sounding bass drum. And, of course, they use a Paiste tam-tam as all of the orchestras in London do. I just don't like the metallic "whang" in the sound of those gongs, as Paiste mixes stainless steel into the alloy. The Philharmonia knows their Mahler, but I just don't like the sound-world they create for Mahler.
As for recordings on one disc, I know we've been over and OVER the pluses/minuses of the Alan Gilbert/Royal Stockholm Phil. one on BIS. But what I like about it is how the two outer movements are proportioned (and the two inner movements don't die either). I would rather hear a quick-ish first movement, and leave plenty of time not to rush the adagio finale. Abbado/Berlin are good in this regard also, but not so well recorded. My zwei groschen on the topic.
