This text offers an in-depth examination of the social history of rock-and-roll. Rockin' in Time emphasizes several main themes, including the importance of African-American culture in the origins and development of rock music, the economy, technology, and the changing demographics of the youth market. Tracing rock from its inception—from American blues to the present—this book shows how rock-and-roll has reflected and sometimes changed American and British culture over the last fifty years.
