Chuck Berry will always be known as one of the founding fathers of Rock n’ Roll. Along with people like Little Richard, Fats Domino, Bo Diddly, Jerry Lee Lewis, Buddy Holly and Elvis Presley - only Lewis is still alive - Berry helped to slim R&B down to a leaner sound and introduce it to a wider audience than it knew in New Orleans (Fats Domino said what they’d been playing what people called rock n’ roll in New Orleans for 15 years).
By the ‘70s he was seen widely as a nostalgia act and no one in their right mind would have turned down a chance to see him in person because he really put on a show, as you can see here.
