Irrepressible duo MC OJ (Otis Frizzell) and the Rhythm Slave (Mark Williams) emerged as teenagers in the first wave of Kiwi hip hop. In the early 1990s they released album What Can We Say? and a series of singles for Murray Cammick's Southside label. After a brief spell in quartet Joint Force, the pair turned their attentions to televison to front the hip hop influenced Mo'Show. Frizzell (son of artist Dick Frizzell) is a prominent graffiti artist and tattooist to the stars, including Robbie Williams; Williams directed the award-winning music video for 'The Catch' by Fat Freddy's Drop, and often performs with the band live.
