This critically acclaimed house DJ/production team, comprising Paul Davis and Matt Jackson, met in a record shop in 1996. They attracted the attention of high-profile DJs (such as Mr C, John Digweed and Tyrant) and critics with a string of 20 melodic and well-produced singles between 1998 and 2000, all enigmatically named after colours. Their debut, the aptly named, Colours received wide praise from all corners of the music press ? The Face magazine made it Album Of The Month and commented: ‘Circulation’s pure house is built for the heart as well as the feet’. Their DJing engagements at clubs such as Bed, Fabric and Renaissance drew similar comment. Unusually, their performances feature a mixture of the duo playing technology ‘live’ and DJing. The sound of their productions appeals to fans of house, trance and techno as it draws influences from all three genres.
