THE BOY WHO INVENTED ROCK AND ROLL
Actually, no one person can claim to have invented rock and roll. The fundamentally
mongrel genre arose from a long-simmering cross-pollination of
black and white musical styles, an evolution that was fueled by the increasing
pervasiveness of music radio broadcasting in America beginning in the 1930s.
The cross-pollination of black and white music had already begun long before the term “rock and roll” (originally African American slang for sexual intercourse)
was ever applied to music, with blues and jazz elements turning up
frequently in white country music, and vice versa.
