Chapter 1 explains the rationale for the book and the principles underlying its methodology. It introduces the two artists covered, Bob Dylan and John Lennon, and the theorists used to contextualise their work: R. Serge Denisoff, Fredric Jameson, J. Anderson Thomson and Clare Aukofer. It summarises the concepts underlying each chapter – dual biography, protest music, history and spirituality – and explores the connections between these themes.
