In 1971, "Swing" magazine named Harriott the Top Producer of 1970. He was one of the first producers to use King Tubby mixing talents at his Waterhouse studio, issuing one of the earliest dub albums in 1974: "Scrub A Dub", credited to The Crystallites. Harriott followed this with another dub/instrumental album, "More Scrubbing The Dub". His late 1970s productions used backing from The Revolutionaries on albums such as Winston McAnuff's "Pick Hits To Click" (1978), DJ Ray I's "Rasta Revival" (1978) and his own "Enter The Chariot" and "Disco 6" (a compilation album featuring Dennis Brown, Cornell Campbell and Horace Andy). In the 1970s he opened his first record shop on King Street in Kingston, later moving to larger premises at Twin Gates Plaza in Half-Way Tree.
