Rostropovich was a great cellist, certainly. But one of his biggest legacies will be the 200+ pieces of cello music composed for him. “He was the recipient of five pieces by Britten; two cello concertos by Shostakovich; and Prokofiev’s Sinfonia Concertante. He gave the first performances of works by Penderecki, Dutilleux, Lutoslawski, Schnittke, Messiaen, Bernstein, Auric and Walton and a host of other 20th-century composers.”
