Karl Bohm was a perfectionist, and these are truly great performances which have aged very well indeed. The Berlin Philharmonic are sumptuous, but not excessively so. This is Mozart for the purist, the collector, and also an excellent starting point for anyone wanting to experience Mozart for the first time. The value is excellent too, six of the greatest Mozart symphonies in classic performances at a good price. And the recordings, decades old, are really very fine:there is a warmth, a mellowness here, very easy on the ear.
On the other hand, this is Bohm's Mozart. A perfectionist yes, but that could also imply sometimes a lack of adventure or too much of an eye for detail, as you might sense if you compared Bohm to say, Bernstein or Karajan. These latter vary tempos much more, and show more dynamism and excitement I think, as well as a little more romance perhaps. So it all depends either on what you think Mozart should be, or simply what sounds you like to hear. Which also brings up the question of instruments: do you like, or should Mozart be played by, a 'modern' orchestra or one which uses only period instruments? And what about the benefits of Mozart recorded by modern crystal clear digital equipment?
Clearly there are questions one can raise about these Bohm Mozart discs, but regardless of whether or not you might feel that one of the great perfectionists has produced a perfect Mozart selection, they are surely a good choice, and definitely excellent value.
