What a voice. He wasn't quite a household name in the U.S. (I think his solo output, especially after his first couple of albums, was probably just too weird for that level of fame), but he was an enormous, acknowledged influence on many acts who were, including Radiohead and David Bowie. There was no one else quite like him.
