Long before rap broke out of the South Bronx, the rude boys in Jamaica were riding the rhythm in their own inimitable style. Call them toasters, boasters, jesters or DJs, their new sound was to change reggae forever. This compilation gathers nine of the best DJs working during reggae's classic period of the mid 1970s and combines them with some crucial rhythms dubbed up by King Tubby in a wild style. Sixteen gems originally released between 1974 and 1977, now reissued on the Blood and Fire label.
