Shostakovich's Symphony No.5 was given its premiere in 1937. It was outwardly in compliance with the ruling party, but the public heard a message of suffering in Shostakovich's masterpiece and it was an unprecedented triumph. Symphony No.12 "The Year 1917" was dedicated to Vladimir Lenin. Both works were premiered by the Leningrad Philharmonic Orchestra under the direction of Yevgeny Mravinsky. The performances featured here were recorded in December 1965.
