This mono performance, recorded in 1955, is not the same one which was released in the Klemperer legacy series (that was a stereo performance, recorded in 1959), but it is far better as an interpretation. The first movement is magnificent and it sounds as though it was recorded in a complete take. The funeral march is a little too fast, and the principal oboe does not sound sad at all, but apart from that I am sure everything is as Beethoven would have wanted it. This is a very well known recording and it deserves special attention. It is a pity that Klemperer slowed down by the time the stereo performance was made, for he ruins the first movement, and therefore the whole symphony, by his plodding tempo. Yet amazingly the stereo recording gets all the acclaim. Avoid it and buy this mono performance.
