Book excerpt: A concise yet comprehensive account of the origins and evolution of rock music, emphasizing its interaction with social change and cultural trends. The narrative begins with ``the birth of the blues'' and proceeds to discuss the major (and mention the minor) performers and to identify the significant styles. These include Fifties rockabilly, folk/protest, the British Invasion, acid rock, punk/New Wave, and Eighties revivalism. Using a lively, anecdotal approach and pertinent quotes, the author examines the appropriate political, economic, technological, or psychological context of each topic, e.g., the relationship between Dylan's music and JFK's New Frontier. A primary focus throughout is on the contributions of blacks and the role of racism. Paul Feehan, Univ. of Miami Lib., Coral Gables, Fla. - Library Journal.
