That every cause has an effect is common knowledge. For Optiv and Mark the cause was drum & bass, and their effect is both indelible and undeniable. Known collectively as Cause4Concern, the crew came together back at the start of 1999, when Optiv was affiliated with Aspect Records, and Mark was working for Vinyl Distribution.
A testament to their talent, it took only a few short months of collaborative creation before they scored their first signing – and not just to any old label – but the massive and seminal Moving Shadow. At the time they were known as nCode, but quickly they had become Cause4Concern and started their own imprint label. The first 12” dropped soon after. Releases on respected labels Tru Playaz, Renegade Hardware, Moving Shadow and Timeless Recordings were to follow, and left little doubt that this was one crew to keep an eye on. Promoters right across the planet couldn’t help but pay attention, and consequently there aren’t many places C4C haven’t performed.
Such was the success of Cause4Concern Recordings that 2001 saw the launch of sister label C4C Limited. Intended as an outlet for experimental tracks and remixes of previous C4C releases by other established artists, the imprint has so far seen input from producers Stakka & Skynet, Teebee, Matrix, Fierce and Rymetyme.
Reformed after a few years of inactivity, 2008 saw Cause 4 Concern return to wreak havoc with their first full length album. The seminal ‘Pandemic’ picked up right where the lads left off – the leading edge of electronic music.

From their London base, they have set about and conquered many different styles of drum & bass, be it on their own family of labels, or via such major players as Virus, Invisible, Quarantine, Playaz and many more. Their performances have graced all parts of the world, and have left crowds stunned and begging for more. Their artistry, versatility and quality are all hallmarks of their dedication to the scene, stretching back some 20+ years.
