Karl has been featured on various albums and labels such as JAL, Sound Assassins and imprints operated by The Nu Energy Collective.

Collaborating with vocalists such as Roza Smart, Pearl Blue and Indigo as well as remixing for artists such as Triple J and Cube::Hard, Karl fuses a unique, in-your-face style with tight production that is pushing the current Hardcore scene above and beyond that tired old trance riff!
