I've purchased a number of Gergiev recordings, all of which are quite exciting. This is the first time I've been let down.
While the playing is great, there's something wrong here with the multichannel mix. I read a review that indicated that the engineers recording this session may have multimiked the hall too aggressively and then tried to make up for it by adding artificial reverb in the mix. I'm not an engineer, but there is a compressed and somewhat flat sound to the recording, even in SACD. I also have an XRCD version of Fritz Reiner's 40 plus year old recording of this piece, which sounds much more dynamic and new.
So while Gergiev is an awesome conductor, this may not be the best version of this particular work.
