Book excerpt: At sixty years old, Bob Dylan is still singing the songs which for forty years have made him one of the most preeminent voices of our time. In this revised and much expanded edition of Stephen Scobie's landmark study of Dylan's work, the author covers all the stages of a remarkable career: from his incandescent impact on the mid-1960s, when Dylan revolutionized folk and popular music, to his later reinvention of himself as a traveling performer-the old blues musician whose work may no longer be fashionable but is still intensely relevant and rewarding.The 1991 edition of Alias Bob Dylan was hailed as a definitive study. The present volume is greatly revised, expanded and updated.
