It’s Mstislav Rostropovich’s 80th birthday. “No soloist in modern times has inspired more new works; no cellist in history did more to expand the instrument’s repertoire. Slava has given about 240 premieres, including concertos by the three Russian masters, the Frenchman Henri Dutilleux, the Estonian Arvo Paert and the Poles Lutoslawski, Panufnik and Penderecki.”
