I agree with J. Scott Morrison that this is a recording of great quality. What is outstanding is the accuracy and precision with which this orchestra follows Mahlers intentions, as marked in the score. Listen to the way in which the symphony opens - how four differnt themes are introduced before the real first theme is "found". Listen too to the way in which tension is built up before the "shock" of the first real climax! This is really deeply reflected music-making.
Some listeners may find the performance too analytical and detailed, too controlled but for me it is this "distance" that makes this symphony even more moving. This sounds like a contradiction but I contend that when performing Mahler one has to maintain a balance. If, for example in the folkmusic-like (Ländler") second movemnet the conductor lets himself be carried away by the paradistic elements the piece can soon sound vulgar. Similarly in the wild, devilish third movment (burlesque) Nott steers his orchestra through this hellish music with a clear sense for the overall structure - it doesn't degenerate into musical chaos.
Mahler filled his scores with detailed instructions. If one follows these musically it isn't necessary to add even more expression. I know that Mahler constantly writes "with expression" and that Bernstein said that one cannot overdo the expression but at the same time Mahler seems to demand a precise musical structure. Self-indulgence on the part of the conductor isn't the key to interpreting Mahler. This new recording with an astonishingly brilliantly playing Bamberger Orchestra achieves exactly this balance between emotionality and control. I didn't miss the "sumptuousness" of the so-called top orchestras one little bit. This is a reflected interpretation with a clear conception and very good sound as well. The sound engineers have done excellent, sensitive work. Like J Scott Morrison I can recommend it wholeheartedly.
