“A theme is the underlying soul of a piece,” says Chinese piano superstar Lang Lang about his second exclusive playlist for Apple Music. “To me the artists on this playlist—whether my mentor Gary Graffman or Vladimir Horowitz, Leonard Bernstein or Daniel Barenboim—are among the all-time greatest masters of classical music. And the tracks included here, as the greatest works of their careers, hold significant meaning for me.” His selections extend to different genres as well, including pop cuts from John Legend and Ariana Grande.
