Bob Dylan has released 34 studio albums, performed countless concerts, and even written a memoir, 2004's Chronicles: Volume 1. Perhaps the only writer who has thought more about Dylan than Dylan is Greil Marcus, the legendary rock critic who has compiled 42 years of his writings about the Minnesota-born troubadour in Bob Dylan (PublicAffairs). While Marcus acknowledges that the waif born Robert Allen Zimmerman will always be pegged as a protest singer from the '60s, thanks to such classics as "Blowin' in the Wind," these essays suggest he's something much more: an iconic figure who has reinvented American music almost as often as he has re-created himself.
