Sonny Boy Williamson was, in many ways, the ultimate blues legend. By the time of his death in 1965, he had been around long enough to have played with Robert Johnson at the start of his career and Eric Clapton, Jimmy Page and Robbie Robertson at the end of it. In between, he drank a lot of whiskey, hoboed around the country, had a successful radio show for 15 years, toured Europe to great acclaim and simply wrote, played and sang some of the greatest blues ever etched into black phonograph records. His delivery was sly, evil and world-weary, while his harp-playing was full of short, rhythmic bursts one minute and powerful, impassioned blowing the next. His songs were chock-full of mordant wit, with largely autobiographical lyrics that hold up to the scrutiny of the printed page. Though he took his namesake from another well-known harmonica player, no one really sounded like him.
