Dmitri Dmitriyevich Shostakovich (25 September [O.S. 12 September] 1906 – 9 August 1975) was a Soviet-era Russian composer and pianist who became internationally known after the premiere of his First Symphony in 1926 and thereafter was regarded as a major composer. Shostakovich achieved early fame in the Soviet Union, but had a complex relationship with its government. His 1934 opera Lady Macbeth of Mtsensk was initially a success but later condemned by the Soviet government, putting his career at risk.
