Brian Eno on why he can't slow down

Brian Eno is a man of many talents - he's known for his days in Roxy music and for working with David Bowie. He's produced many at the top of the musical industry and is also recognised as the architect of "ambient music". This week is a busy one for him. He has an album out and an art show with light and sound installations. Krishnan Guru-Murthy went to meet him.
