There are at least eight artists with the name Matrix: 1. 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.
