"In Positive Vibrations, Borthwick's excellent new history of reggae music–the putative soundtrack of Rastafarianism–and its historical and political importance since its inception in the early 1960s, the author demonstrates respect for the music and the faith that inspired it even as he examines the flaws and contradictions in both. . . . They aren't likely to read a lot on summer break, but I think the world would be a better place if every college kid grooving to Marley, Peter Tosh, Burning Spear, and others took the time to learn there's a lot of heart behind the soul of their poolside-kegger soundtrack. Positive Vibrations is a good place to start."– "Washington Independent Review of Books"
