Brian Setzer... so much of what we do now started in 1954 at Sun Records in Memphis Tennessee ... those guys were inventing that stuff (Rock & Roll) ... you can really tell on some tracks ... they were actually afraid at times of what they were playing. But Rock & Roll definitely didn't come before that time; it started right there
