There’s little original Dylan footage and no music in this unofficial bio co-produced by the fanzine Isis. But what we do get is a series of fascinating new interviews?with old school friends and teachers in Hibbing who describe a loner who gave little hint of the extraordinary gifts he was later to develop, early colleagues who played with him in Greenwich Village and leading Dylanologists such as Clinton Heylin and CP Lee.
