Will Gompertz

He was made the BBC's arts editor in 2009. In this capacity he has interviewed the likes of Mick Jagger and Elton John. He also wrote and presented the main evening news obituaries for performers including David Bowie, Prince, Leonard Cohen and George Michael.

I think you could say along with Elvis Presley, The Beatles, the Stones (The Rolling Stones), David Bowie is one of the very few people who defined what pop music is and could be.
