This book examines the American Sixties, and how that period’s socio-political essence was reflected and refracted in certain forms of the period’s music. Its five main chapters bear the names of familiar musical categories: ’Folk,’ ‘Rock,’ ‘Jazz,’ ‘Avant-Garde,’ ‘Classical.’ But the book’s real subject matter—treated at length in the Prologue and the Epilogue but spread throughout all that comes between—is the Sixties’ tangled mess of hopes and frustrations, of hungers as much for self-identity as for self-indulgence, of crises of conscience that bothered Americans of almost all ages and regardless of political persuasion.
