Mariinsky Theatre Orchestra

In 1935 Joseph Stalin changed its name (and that of the Ballet) to the Kirov, after Sergei Kirov, the first secretary of the Communist Party in Leningrad, whose 1934 murder by his regime Stalin was attempting to whitewash. After the collapse of the Soviet Union, the name was changed to its current one in 1992.
The current artistic and general director of the Mariinsky Theatre is the conductor Valery Gergiev. Under Gergiev, the Mariinsky Orchestra has become one of the leading symphony orchestras in Russia. Provided by Wikipedia
