O.B. has been rapping for about 10 years in Sydney, and has now played across Australia. He was a mumbling presence alongside DJ A.L.F. at the legandary Joined at the Bass sessions at the Cricketer's Arms, until the Rum Corps (aka the NSW Police Force) and a yuppie shut down the live music one fateful Christmas eve. They could not, however, stop Alf and Ozi from forging a musical partnership that has taken them everywhere from dingy suburban pokie palaces, bush doofs, kiddiecore raves and the metro's stage.
