He has always been a darling of the critics and his legion of loyal fans, but if there were any justice in the music world, Rufus Wainwright would be as big a star as Elton John by now. The gifted son of folk legends Kate McGarrigle and Loudon Wainwright III was already marked for greatness by the time he released his debut album in 1998. The baroque musical stylings and swooping tenor vocals were a perfect match for his witty, articulate songwriting. It set a template that he expanded on with his later albums, including two of the boldest albums of the '00s, Want One and Want Two.
