Undefined first started playing in clubs alongside Maddix and Marty J in the Christchurch DJ trio Ill Def. After forming in 2007 and mixing together for about a year, Ill Def began supporting local acts in the Christchurch scene and have since built up an impressive following. Having left Christchurch at the start of 2012 and setting up in Melbourne, Undefined is now smashing out dance floors down under while promoting local and international Drum & Bass acts through The Tech Collective.
