Prokoviev’s youthful Piano Concerto No. 2 was a place for more biting heroism. Matsuev produced the tone of a powerful gong, and the beautiful opening tune rang like a great summons. It was a summons for a spectacular bruising as he later dominated the piano with astonishing force. For his encore, Liadov’s “The Music Box,” Matsuev released yet another Russian secret weapon, the ability to electrify upper registers of the piano with mere finger power.
