Benjamin Grosvenor was born in 1992 in a town just outside London. Everyone assumed that he would follow family tradition and play the piano. No one expected that he would perform in front of thousands at the BBC Proms in London. On Performance Today, we'll hear Grosvenor's second star turn at the Proms with a concerto by Camille Saint-Saens. And Brian Newhouse will preview the famous Last Night of the Proms concert he's hosting this weekend.
