Bob Dylan's lyrics are at once abstruse and evocative, urgent and timeless. But, as Mike Marqusee's compelling study makes clear, behind the anarchy and playfulness of Dylan's imagery lie meanings that are often highly charged with political and social concerns. It was blues and folk songs that first led Bob Dylan to politics. But it was politics that unlocked his own astonishing songwriting ability, evidenced by dazzling responses in the early 1960s to the civil rights movement and the threat of nuclear war. Marqusee traces the young song-writer's subsequent reluctance to be pigeonholed, his rejection of protest, and his turn to electric rock at the Newport Folk Festival in 1965. He shows the way folk tradition, modernism, and commercial popular culture are sublimely fused in Dylan's masterworks of the mid-1960s, notably on the albums Highway 61 Revisited and Blonde on Blonde, and discusses the artist's quest for American identity-amid the continuing carnage in Vietnam and growing chaos at home - in The Basement Tapes.
