Todd Rundgren's best-known songs -- "I Saw the Light,"  "Hello, It's Me"  "Can We Still Be Friends," and  "Bang on the Drum All Day" -- suggest that he is a talented pop craftsman, but nothing more than that. Rundgren is a rock & roll maverick. Once he had a taste of success he chose to abandon stardom and, with it, conventional pop music. He began a course through uncharted musical territory, becoming a pioneer not only in electronic music, computer software, and Internet music delivery as well.
