Tetrack consists of the childhood friends Carlton Hines, Dave Harvey & Paul Mangaroo. They started singing together in the early 70's and in 1972 the set officially as a vocal trio, taking the name Tetrack from the Sound System »Tetrack HiFi« that used to play across the road of Dave Harveys yard.

In 1974 they were introduced to Augustus Pablo by a friend of Pablos, Densie, who one afternoon heard them practicing. Their first LP was released in 1980 on the Message label and is generally considered a classic of the roots genre.

For their sophomore album they worked with Gussie Clarke and released a Showcase by the name of Trouble.
