2013 marks 15 years of Ed Rush & Optical's Virus Recordings, one of the most important when you're talking about the expansion of the neurofunk side of drum & bass. Both Ed Rush and Optical were under Goldie's Metalheadz wing at one time, but as their sound grew (and they started producing together), the need for a home for their explorations was apparent. Their experiments in the deeper, darker regions of drum & bass turned into a solid batch of important releases, from the duo as well as artists like Matrix, Cause 4 Concern, Sonic & Silver, Audio, and Optiv & BTK.

While we're not sure of Virus putting out any special compilations to mark the anniversary (although Ed and Optical have been touring, doing special sets to mark this event), DAD decided to look back at the best tracks from the imprint. Our aim was to highlight tracks that had been released unmixed, as the duo had a tendency to throw out mix CDs with unreleased gems (sorry, "Bleep Bleep"). Relive the bangers from this legendary imprint.
