When reggae spun off into the more controversial genre known as "dancehall", a distance grew between the fans of the new sound and the "roots reggae" of yesteryear. Norman Stolzoff, an anthropologist, took a look at the gap between these two now-distinct genres, and the economic, social and political contexts that brought them apart. Though this is a serious cultural study, it's definitely readable, and definitely worth a perusal for both fans of reggae and fans of social psychology and its convergence with ethnomusicology.
