Lang Lang has become a global brand name. This year, the piano superstar has hobnobbed in Davos, appeared at the Nobel Peace Prize Ceremony in Oslo, organized a Haiti earthquake benefit at Carnegie Hall, and launched his own line of Steinway student pianos.

Lang joins us for two performances: one on WNYC's Steinway grand and another on his iPad. He tells us whether mobile technology can hold any serious music-making potential and previews his upcoming appearance with the New York Philharmonic in Central Park.

Watch Lang Lang perform on his iPad below.
