Legendary blues guitarist Hubert Sumlin died of heart failure at a hospital in Wayne, New Jersey, last night, December 4. He was 80. As bluesman Howlin' Wolf's guitarist in the 1950s, Sumlin influenced several generations of blues and rock guitarists, including Eric Clapton, Stevie Ray Vaughan and Jimmy Page. What made Sumlin's resume even more impressive was that he also was Muddy Waters' for a brief period in the mid-'50s before rejoining Howlin' Wolf's band.
