My Moscow relatives were jealous when I told them I would hear Denis Matsuev play Rachmaninoff’s Third Piano Concerto at the Maison symphonique Thursday, and these are not easy people to impress. I had one cousin train an elephant to walk a tightrope between two balconies at a party — a three-ton beast, bejazzled in every way, who loped across with a triumphant teenager on top — and nobody noticed.
