Dancer and occasional singer in The Prodigy.

In the late 1980s Flint met DJ Liam Howlett in a rave club and expressed his appreciation of Howlett's taste in music. After receiving a mixtape from Howlett, Flint came back with great enthusiasm, insisting that Howlett should be playing his tracks up on stage, and that Flint, along with friend Leeroy Thornhill, would dance to them.
Originally Flint was the band's dancer, but in 1996 he featured as the vocalist on the hit single "Firestarter". The accompanying video showcased Flint's new punk look. This trend continued with the next Prodigy single "Breathe", on which Flint performed the backing vocals, whilst Maxim performed lead. The 1997 album The Fat of the Land featured Flint's vocal contributions to several tracks, namely "Breathe", "Serial Thrilla", "Fuel My Fire" and "Firestarter". In 2002 the single "Baby's Got a Temper" was released. On the next Prodigy album, Always Outnumbered, Never Outgunned (2004), Flint did not perform any vocals, although he did appear on the "Hotride – El Batori Mix," on the "Hotride" single. The latest Prodigy album, Invaders Must Die, was released on 23 February 2009 and features vocals by Flint on multiple tracks, including; Take Me to the Hospital, Run with the Wolves and Colours. Flint released a single titled "War" with dubstep artist Caspa in 2012.

Flint is a keen motorcyclist. He rode the 1500 miles from Britain to Southern Spain to attend the 2007 Spanish motorcycle Grand Prix, and also races in club competitions. He now has his own motorcycle team, 'Team Traction Control' which he races in the 2011 Hottrax Endurance events. Flint is also a supporter of London football team West Ham United.
