In 2006 Jimmy Mofo started the Beat Assassins along with Joe Lenzie, they became a fundamental part of the Breaks scene and won various awards. They spent the early days as a duo touring various parts of the world and created their own record label Mofo Recordings as an outlet to release music.
In 2010 Jimmy & Joe amicably parted ways. As the ever popular breaks scene started dying down Jimmy moved onto a Trap / Grime project with DJ Sai called Koshii.
In 2016 Jimmy went back to his roots and started producing drum n bass music under the Beat Assassins name.
