The primary attraction of this video is that it provides a visual document of some of the greatest German conductors of the century. For those interested in how a conductor "looked" when leading an orchestra, this is an interesting documentary (particuarly for Furtwangler, whose style is the definition of idiosyncratic). The performances are uniformly superb, and provide a captivating contrast with the orchestral style heard(and seen) today in most major symphonies. Therefore, as a muscial document, this video is highly recommended.
However, as a historical documentary, it is deeply flawed. There is no narration, and only minimal information on the subtitles. Historical context is also missing from most of the performances. Because this video is a release from a company specializing in musical performances and not history, this is perhaps not surprising, however it is disappointing.
Equally disappointing is the booklet by "expert" Frederic Spotts. Spotts suffers from a failing common to many of those who write about virtually anything related to the Third Reich. He presents a cartoon image of the persons described (in this case the conductors who chose to remain in Germany under Nazi rule), and therefore does nothing to help understand how such a monstrous regime could gain power in a country like Germany. Perhaps this is asking too much from a sixteen page booklet, however besides basic biographical information, this booklet is completely dispensible.
One final criticism. I realize that musical performances from wartime Germany are perhaps quite rare, but couldn't the documentary makers have considered other performances besides the 800 "Meistersinger" preludes included here?
All that being said, there is one performance that is worth the price of admission. Wilhelm Furtwangeler conducting the Berlin Philharmonic at the AEG factory in 1942 is simply fascinating. The performance is spectacular, the image of the symphony performing in front of Nazi banners is deeply disturbing, and the extended views of the factory workers, whose faces seem to show the first signs of recognition that Germany will lose the war, are not to be missed.
