Mad Doctor X

the undercover alter-ego of hip-hop veteran DJ Jason Tunbridge (aka Xavier Jones, Funk Wizard Jay Rock, DJ Jason, Monty Props). 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.
