Many thanks for this clip, my Lord.
Rostropovich and Seiji Ozawa made a lot of interesting recordings together. Their recording of the Second Cello Concerto by Shostakovich on Deutsche Grammophon is my favourite recording of that piece. I've always liked the Second Concerto better than the First.
At the moment, I'm listening to a rather obscure recording by Rostropovich and Ozawa of the
Triptique by Renaud Gagneux and
Soto voce by Rodion Shchedrin for cello, orchestra and recorders (!). Not very great or important works, but interesting enough to hear now and then.
