Thanks Gil. The "Muddle Instead of Music" you refer to was a Pravda article about his opera "Lady Macbeth of Mtsensk," after Stalin attended a performance and left after the first act. This caused Shostakovich to withdraw the 4th from its scheduled performance in Leningrad in December 1936. He no doubt had visions of being shipped off to Siberia in the middle of the night (or worse). It was premiered well after Stalin's death, in 1961.

Shostakovich 1rst Symphony has that iconic timpani solo at the end. C to D to Eflat roll
