This 90 minute film tells the extraordinary story of a concert took place at the height of the Siege of Leningrad in 1942. A year before the Germans had begun the deadliest blockade in history which would kill three quarters of a million civilians. Now, a group of starving musicians assembled to perform Dmitri Shostakovich’s 7th Symphony in what would become a defiant moment in the city’s survival. Historian Amanda Vickery and BBC Radio 3 presenter Tom Service reveal the story of triumph of the human spirit over unspeakable barbarity. The film is interwoven with excerpts of the symphony performed specially by the St Petersburg Symphony Orchestra at the Philharmonic Hall in St Petersburg where the concert took place, conducted by Maxim Shostakovich, the composer’s son.
