Mad Doctor X has been played on NTS in shows including Cool World West w/ Coolwater, featured first on 18 March 2019. Songs played include Nemesis.

The undercover alter-ego of incredible Bruce Banna-like hip-hop veteran DJ Jason Carter (aka Xavier Jones, Funk Wizard Jay Rock, DJ Jason, Monty Props, Jazzy Jason). . On the scene for years since he first blew up with Blapps Posse and 'Don't Hold Back' (released in 1990 and repressed 57 times since) the Mad Doctor X has been busy working in the lab conducting his illicit experiments and concocting his ill beats in various disguises ever since: London Funk Allstars and DJ Toolz on Ninja Tune, Clusterfunk on Cooltempo, and most recently as Mad Doctor X on Freskanova. He may also be familiar as the man providing all the scratches on The Freestylers' recent records. You know this man: you just don't know you know him.
