Medeiros's debut as a recording artist under his current stage name came with the song "The Life of Brian," produced by Noel Zancanella. The track later appeared on The Procussions' 2005 album Up All Night.
In addition to his solo work, Medeiros DJ'd for the local hip-hop group T.I.O., through which he met Qq and TMAL. These collaborations led to the formation of The Procussions. Medeiros was also active in the B-boy and B-girl scene as a member of the dance crews T.S.F. and Bomb City Breakers.
