The coming of rock 'n' roll made the guitar king: Chuck Berry, discovered by Muddy Waters, became a teen idol through both his inventive songwriting and his distinctive electric guitar style, while Elvis Presley, who played acoustic guitar, was backed by Scotty Moore, a Memphian who played in a tradition begun by Paul Burlison, another white Memphis guitarist who had worked with bluesman Howlin' Wolf. Wolf later discovered a teenager named Hubert Sumlin, whose wild, distorted sound became the backbone of Wolf's band.
