Author Chris Gregory discusses his latest book - Minstrel Boy: The Metamorphoses of Bob Dylan. Bob Dylan is one of the major cultural figures of the modern age, combining a reverence for the traditions of many forms of American music with a distinctly postmodern sensibility. It is no exaggeration to state that he has revolutionised the art of poetic song writing. He is a recipient of the Nobel Prize for Literature, the Pulitzer Prize and numerous other awards, as well as being arguably the most influential single artist in the history of rock music.
