Mstislav Rostropovich: The Indomitable Bow (2018)

Rostropovich, who had already achieved international recognition in the 1950s, was forced to flee his country in 1972. He defended Solzhenitsyn who was expelled from the USSR for having published the "Gulag archipelago". Deprived from of his citizenship by the Soviet authorities, Rostropovich settled in Paris and Washington. This gave birth to his legend.
