David Bowie.
The man has invented and re-invented himself for over 30 years, he is a major major artist. I believe he is one of the greatest of all Rock figures, and a major influence on countless others.
Having said that I also realize, that both Lou and Iggy were big influences on Bowie, and in return he gave both their careers major kick's up the arse in the early '70's. Transformer and Berlin being big fave's of mine.
As the poll was for Lou and not the Velvets his career has been somewhat more spotty, not withstanding his occasional great album, the two above and also New York.
