Starting in the 1970s, Parks made repeated excursions into Afro-Caribbean music, notably on his 1972 album "Discover America" and on records he produced for the Esso Trinidad Steel Band and Mighty Sparrow. At the same time, he managed the audio/visual department of Warner Bros. Records, which was the earliest of its kind to produce music videos for artists. Since then, he established himself in motion pictures and over the years has directed, arranged, produced, and composed soundtracks for theatrical films and television shows such as "Popeye" (1980), "" (1985), and "The Brave Little Toaster" (1987). Much of his later work has been in commissioned orchestral arrangements for lesser-known indie acts.
