Moving to the United States when he was twelve years old, Kutmah grew up in Hollywood, California and ultimately made a name for himself as a talented underground artist & DJ. Intrinsic member of eclectic Los Angeles-based music collective 'Dublab', in 2004 Kutmah launched the seminal club 'Sketchbook', which forged fundamental foots of the now-infamous LA beat scene. In Spring 2010 without advance warning nor any provoking criminal activity, armed US Federal agents entered Kutmah's home, incarcerated him for two months at a New Mexico detention center under immigration charges, and ultimately deported him to the UK where he currently resides.
