King emerged in the early 1990s, performing on sound systems, with a gruff vocal style similar to Buju Banton's.[1] After several hit singles in Jamaica, he had some international success with "Work", a combination single with Barrington Levy. He topped the Jamaican singles chart in 1996 with "Sweet Sensimella", a duet with British singer Jamie Irie. His other hits include "Butterfly", "Rail Up", "Haffi Get You Body", "Gal A Fuss Gal A Fight", "Real Ting" (with Tony Curtis), and "Question Ask" (with Freddie McGregor).

In 2007 he was found guilty of disorderly conduct and fined $4,000 after verbally attacking the Queen of England and the Jamaican police on stage during his performance at Curefest in Trelawny.
