Since Renegade Hardware first picked up an Unknown Error tune back in 2004, there's been no stopping the born and raised Kent collective. Unknown Error burst onto the scene with their debut release of "Shadows" on Renegade Hardware in January 2005 which featured on Hardware's first release of 2005, The Chronicles vol.4 EP. This release went straight in at no.8 in the BBC 1Xtra DnB Charts and was featured on the Guerrilla Warfare CD mixed by Grooverider. Tracks on Trouble On Vinyl, Cymbalism and one of Moving Shadow's strongest EPs followed to take Unknown Error far beyond being newcomers.
