Kirsty Young's castaway is the Chinese pianist Lang Lang.

He was five years old when he gave his first public recital in front of an audience of 800 people. It was a pivotal moment and from that point on it was clear where his future lay. His parents were both musical too but, during the cultural revolution, had not been able to pursue their own ambitions. Lang Lang was born under the one-child rule and so he was, he says, their only chance. Their aim was that he should become the No.1 pianist in China and in the years that followed, family life was sacrificed to that end.

Still only 28 years old, he is a phenomenon in the classical music world - he played to a global audience of four and a half billion people for the opening ceremony of the Beijing Olympics and, when he returns to China, he says he is mobbed in the streets.
