Cellist and conductor Mstislav Rostropovich died today in Moscow. Tim Page wrote a fine WaPo obituary. YouTube has a relatively small collection of Slava-iana, but does include such delectable moments such as Rostropovich playing the Dvorak concerto with Carlo Maria Giulini and the London Philharmonic, and he himself conducting the Tuba Mirum portion of Britten's War Requiem in his utilitarian conducting manner. Other Rostropovich YouTube clips are here. And Alex has a sound clip of Rostropovich playing part of Britten's First Cello Suite.
WFMT's Peter Whorf has posted an attractive archive of Slava-iana. Three youtube clips (Bach, Brahms, the finale of the Dvorak concerto) fall between two radio interviews. "'I tell this musician'-who only played mezzo-forte and fortissimo-'you not true musician, you just mezzo-fortiste,'" Shostakovich once told Rostropovich.
