Book excerpt: A brilliantly written and groundbreaking book about Dylan's music – now the recipient of the Nobel Prize for Literature 2016 – and its musical, political and cultural roots in early 20th-century America Growing up in Greenwich Village in the 1960s Sean Wilentz discovered the music of Bob Dylan as a young teenager. Almost half a century later, now a distinguished professor of American history, he revisits Dylan's work with the critical skills of a scholar and the passion of a fan. Drawing partly on his work as the current historian-in-residence on Dylan's official website, Sean Wilentz provides a unique blend of biography, memoir and analysis in a book which, much like its subject, shifts gears and changes shape as the occasion demands.
