What was it about Bob Marley that made him so popular in a world dominated by rock 'n' roll? How is it that he not only has remained the single most successful reggae artist ever, but also has become a shining beacon of radicalism and peace to generation after generation of fans?

The man who introduced reggae to a worldwide audience, Marley was a hero figure in the classic, mythological sense. From immensely humble beginnings, with talent and religious belief his only weapons, the Jamaican recording artist applied himself with unstinting perseverance to spreading his prophetic musical message across the globe. In 1980, on tour, Bob Marley and the Wailers played to the largest audiences a musical act had ever experienced in Europe. Less than a year later, Marley would die, only thirty-six years old. Sales of Marley's albums before his death were spectacular; in the years since he died, they have been phenomenal.

Chris Salewicz, the bestselling author of "Redemption Song," the classic biography of Joe Strummer, interviewed Bob Marley in Jamaica in 1979. Now, for the first time, in this thorough, detailed account of Marley's life and the world in which he grew up and which he came to dominate, Salewicz brings to life not only the Rastafari religion and the musical scene in Jamaica, but also the spirit of the man himself. Interviews with dozens of people who knew Marley and have never spoken before are woven through the narrative as Salewicz seeks to explain why Marley has become such an enigmatic and heroic figure, loved by millions all over the world.
