Though it's a topic of great debate among reggae enthusiasts as to who actually invented the concept and subsequent genre of dub, it's inarguable that King Tubby, if not the creator of dub, is at the very least one of its most valuable innovators. Tubby's distinct remix style touched almost all major (and many lesser-known) players in the golden age of '70s roots reggae. Tirelessly prolific, Tubby accrued untold stockpiles of mixes and dubplates that saw eventual release over the years. King Tubby's dub art began to flower on remixes for producer Bunny Lee. The engineer treated hundreds of Lee productions between 1973-1975, establishing dub as a independent style in reggae music in the process. While protégés and future dub stars Prince Jammy and Scientist would eventually remix some of the Lee dub tracks under Tubby's name, the sides on Roots of Dub are all done by Tubby himself. As the title implies, one hears the beginnings of his original dub style: a soundscape made up more by spare yet innovative deconstructions of the original sides than by the many added sound effects heard on future mixes. And while a handful of Tubby discs suffer from second-rate material, this collection stands out with some of the choicest of Lee's rhythm tracks. No small credit for this quality goes to Lee's amazing early reggae house band, the Aggrovators, which featured bassist Robbie Shakepeare, drummer Carlton "Santa" Davis, and guitarist Earl "Chinna" Smith, among others. A fine introduction to this artist's catalogue.
