That every cause has an effect is common knowledge. For Optiv, Mark and Stuart, the cause is drum & bass, and their effect is both indelible and undeniable. Known collectively as Cause 4 Concern, the crew came together back at the start of 1999, when Optiv was affiliated with Aspect Records, and Stuart and Mark were 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 by July they had become Cause 4 Concern and started their own imprint label.
