Watch the Stone Berry: Solo online guitar lesson by Joe Deloro from Blues Rock Road Trip
In 1958 Leonard Chess traveled from Chicago to London to sign a distribution deal for Chess Records with Decca Records. It was a first for American Blues in England, since Chess recordings were available only as imports before. Muddy Waters also toured that year and shook up young audiences with his electric sound and style. By 1962 much of the Chess Blues roster would visit England and Europe annually, billed as the American Folk Blues Festival. This gave the future members of The Rolling Stones and other aspiring British Blues musicians much of what they needed to base themselves on and get going.
Meanwhile, besides the Blues, Rock & Roll was on the rise with Chuck Berry as its' guitar ambassador into the early 60's. And then the torch was passed. Just as Chuck had modernized the guitar style of Carl Hogan and others for the youth of the mid-50's, Keith Richards did the same with Berry's style and others for the next generation in the mid-60's.
In retrospect, it should be clear that without Keith's efforts, the 50's-60's guitar connection would certainly have been diminished at best. Obviously, things went well. By the time of The Stones first album he had enough of it down cold. Just listen to his fill licks in Bobby Troup's "Route 66" and Berry's "Carol" for example. So, Leonard's low-key business trip to London made Blues-Rock's next connection.
