MC Duke (later just Duke) was a British rapper from the East End of London, who recorded with DJ Leader 1. He was one of the pioneers of the early British hardcore sound and later went on to record as IC3.
Duke began his career at a DMC World Championships after show party, where the winner of the MC battle competition got on stage and boasted that he would beat any rapper who challenged him. Duke climbed on stage to take the challenge, and emerged victorious. The battle was witnessed by Derek Bowland, who was acting as an A&R man for Music of Life records. He quickly arranged a meeting between Duke and Simon Harris, the head of the record label, where instead of bringing a demo tape, Duke rapped live in Harris' office. Harris agreed to sign him.
He debuted with the track "Jus-Dis" on the compilation album Hard as Hell (Music of Life, 1987) - an album which also included Overlord X's first track before he was later signed by Mango Records: in later years, Duke and X would develop a grudge that led to both recording records to belittle the other. In 1988 Duke was support to Salt-N-Pepa on their UK tour.
A series of singles followed, with Duke finally pairing with longtime partner DJ Leader 1 (sometimes DJ Leader One) on the single "Throw Your Hands in The Air" (Music of Life, 1989) and adding his name to the sleeve with Duke right up to their reincarnation as IC3 for the EPs Excalibur (Shut Up and Dance, 1992) and Untitled (Shut Up and Dance, 1992).
