Lady Macbeth of the Mtsensk District
Within weeks "Quiet Flows the Don" was proclaimed a model of socialist realism in music and won Dzerzhinsky a Stalin Prize (Stalin saw Shostakovich's opera "Lady Macbeth of the Mtsensk District" at the same theater nine days after attending "Quiet Flows the Don". His disapproval of Shostakovich's opera set the stage for its composer's official denunciation, which lasted until Shostakovich wrote his Fifth Symphony.)
