Earlier, however, his skills were vital in enabling the orchestra to partner Murray Perahia in Beethoven's Third Piano Concerto with such distinction.

They mattered not one jot, for once he had relaxed a little, he gave a display of fine piano playing, with an opening movement of stormy grandeur, a slow movement of intense poignancy, and a finale which teasingly leaned this way and that with unfettered virtuosic joy. And, as usual, not a single ugly sound.
