He began working at Randy's Record Store, his father's business, and began helping make the associated studio, Randy's Studio 17, one of the most important Jamaican studios of the early 1970s.
Chin's first major commercial success was Java, an international hit by Augustus Pablo. He had further local hits with Dennis Brown's "Cheater", and Junior Byles' "King of Babylon", and produced Pablo's debut album, This Is Augustus Pablo. Chin produced the Java Java Dub album in 1973, which he claims was the first ever dub album. Further local hits followed with Carl Malcolm's "Miss Wire Waist" and "Fattie Bum Bum", which, with the help of Jonathan King, became a UK chart hit in 1975, reaching #8.
After his family business moved to New York City, Chin spent some fifteen years running a Jamaican restaurant in Queens. He began producing again in 1998.
In 2007 VP Records started an imprint 17 North Parade to reissue some of the historic Randy's releases.
