Piano prodigy Benjamin Grosvenor on Marr

9 October 2011 Last updated at 14:45 BST

Benjamin Grosvenor first emerged on the national stage at the age of 11, as a finalist in the BBC Young Musician of the Year competition, in 2004 - astonishing the judges and audience with his maturity and technique.

He went on to study at the Royal Academy of Music and, this summer, at still only 19, he was the youngest soloist ever to play at the first night of the Proms.

Here he performs Morton Gould's 'Boogie Woogie Etude'.
