Mstislav Leopoldovich "Slava" Rostropovich was a Soviet and Russian cellist and conductor. He is considered to be one of the greatest cellists of the 20th century. In addition to his interpretations and technique, he was well known for both inspiring and commissioning new works, which enlarged the cello repertoire more than any cellist before or since. He inspired and premiered over 100 pieces, forming long-standing friendships and artistic partnerships with composers including Dmitri Shostakovich, Sergei Prokofiev, Henri Dutilleux, Witold Lutosławski, Olivier Messiaen, Luciano Berio, Krzysztof Penderecki, Alfred Schnittke, Norbert Moret, Andreas Makris, Leonard Bernstein and Benjamin Britten.
