4. B.B. King
One of the most prolific musicians of all time and hands-down one of the greatest guitar players of all time, B.B. King is hailed as "The King of Blues." And while his style of playing has influenced almost every blues and rock musician who came after him, it's also his amazing wardrobe that's made him one of the best showmen we'll ever see. His clothes perfectly walk the line between showmanship and gaudy, and never outshine his music. B.B. King started recording and performing in 1949 and is still going strong, making his reign as King longer than most.
