Greil Marcus has gone from rabblerousing rock critic at magazines like Rolling Stone and Creem to one of our most respected masters of scholarship and prose, serving on the board of the National Book Critics Circle and co-editing A New Literary History of America for Harvard University Press a few years ago.
