Matrix is the pseudonym of London based drum and bass producer and DJ Jamie Quinn. Quinn started his musical career as one half of drum and bass duo Turbosound, who signed to DJ SS's F Project Records label, an offshoot of Formation Records. Their name was changed for them to "International Rudeboys", which while it perhaps didn't suit them as well as they would have liked, nonetheless this brought further success on Formation Records proper. Later, Jamie began to release solo work as Matrix on various other Drum and Bass labels, beginning around 1994. Since then he has DJed worldwide and produced many records, including several for his own label, Metro Recordings. His brother, Matt, is also famous in the drum and bass world as Optical. His debut LP as Matrix, Sleepwalk, was released on his brother's label Virus Recordings in 2000. Further collaborations saw him make a foray into house music as one half of Goldtrix, who had a UK top ten hit with the single "Trippin".
