Whatever you may think of his slightly offbeat style or flamboyant stage manner, there can be no denying that pianist Lang Lang is bringing people back to classical music in droves with a devastating combination of “charm, charisma, stamina and an almost evangelical sense of mission… As far as Lang Lang is concerned, changing the world means you don’t just play concerts, you also appear on The Tonight Show and Sesame Street.” His open embrace of all the publicity that has come his way in recent years has led to an unusually bitter critical backlash, but none of the sniping seems to have dimished the pianist’s confidence or ability in the slightest.
