For those interested, here's a follow-up to my Berlin 1953 youtube video:
The music is, again, from Shostakovich's brilliantly cinematic 11th Symphony.
That symphony, composed late in 1956, was entitled "The Year 1905" - and was supposed to commemorate the abortive Russian revolution of that year.
But the composer is said to have remarked that what he really had in mind in this work was the tendency of events in Russian history to repeat themselves...
...which, in light of its time of composition, has given rise to persistent rumors that what it's really all about is the even more horrific & tragic Hungarian revolution of 1956.
So the visuals here, mostly taken from news-reels of the day, are particularly appropriate.
