The pair first met in 1987, both living on Blackbird Leys estate in Oxford, England and brought together through a mutual love of hip hop. Distracted by the arrival of hardcore in the early nineties, record collecting was quickly followed by DJing and eventually production. Greenhalgh was the first into the studio, with "Freestyle Fanatic" launching his career in 1991. However it was the establishment of the Legend imprint and specifically Greenhalgh's "Champion Sound", which took their profile beyond the many anonymous white labels that were dominating the music at the time. In 1994, the pair started recording together, with "Got to Believe" the first in a series of records which pushed the label away from the darkside movement and more towards the epic string sections and rolling beats which started to appear on labels like Lucky Spin, Basement and Good Looking. After six years of recording singles for others, the pair established the CIA label in the closing months of 1997 with the help of Brillo from Timeless Recordings. The release of their Silent Reign EP for Goldie's Metalheadz breathed a new lease of life into the project, and the pair achieved a further boost with a well-timed Bad Company remix of "Champion Sound" which conjured further interest in what they were doing at their own label. Their debut album Advance exposed a further field of interest, with downtempo experiments logged as a series of "Breaks" on the majority of their early EPs extended to some deep house, this breadth taken a step further with their Skin Deep imprint which has forged broken beat to considerable acclaim. Their pioneering[dubious– discuss] of a revival in old school sounds and arrangements, together with Digital and Reinforced, dominated drum & bass throughout 2001.
