When the cellist Mstislav Rostropovich died in 2007, the world lost not only a great musician, but also a personality who had earned the title "World Citizen" with political commitment and commitment to humanitarian goals. As an initiator of new works, as a pedagogue and conductor, he left significant traces in the history of music. In 2017, the great musician would have turned 90 years old. At the same time, we mark 10th anniversary of his death. The double-album The Sound of Mstislav Rostropovich contains legendary elements from his huge discography.
