In the context of Dmitri Shostakovich, the " controversy" arises from a volume of memoirs, titled Testimony, published in New York in 1979, four years after the great composer's death. It recounts his sufferings under Stalin, his repudiation of communism, his caustic deprecation of famous colleagues. The memoirs were "related to and edited" by Solomon Volkov, a Leningrad musician who emigrated to the US in 1976.
