I think I have a faint memory that I heard a concerto in stereo by Karajan
from Berlin in 1944, you could hear the anti - aircraft artillery in the
back. They said it was the first stereo recording and it was a tape released
by the Russians who took it at the end of the war. I don't remember if it
was a Beethoven or Brahms symphony. It was sent in the Swedish radio P2.
