Deejay Jah Thomas was one of the creative figures making a dramatic impact on the Kingston sound system scene of the late 1970s and early 80s, the rhythms he laid at Channel One studio with the Roots Radics helping to steer reggae towards the emerging dancehall style. Voicing and mixing his work at King Tubby’s studio, typically with the young upstart engineer known as Scientist, Thomas was another champion in the realm of dub, his re-makes of vintage Studio One and Treasure Isle rhythms part of the process. In A Dub Explosion is a thrilling comp of tough dubs, mixed by Scientist & the King.
