Pianist and composer Conrad Tao is the only classical musician on Forbes' 2011 "30 Under 30" list of people changing the world. In 2004, CPR Classical host David Rutherford interviewed then 10-year-old Tao at the Aspen Music Festival and School, where Tao was a student.

On Sept. 12, Rutherford was once again joined by Tao, now 19, in the CPR Performance Studio for an interview and a performance of the pianist's own composition, "Iridescence for Piano and iPad."

The young composer performs a piece of his own composition, written for piano and... iPad.
