Jules O'Riordan was born in London on 26th October 1965 in North London. While still a law student at LSE ,Jules began his long time association with Norman Jay. Together they promoted Shake n Fingerpop and Family Funktion which established them as a central figure of those Rare Groove days, breaking into abandoned warehouses to stage "warehouse parties." It was Norman who applied the JUDGE title to JULES "It was Jays preconceived thought that here was a student hed met doing a degree in law that could only turn out to be a judge. When the police turned up at their illicit gatherings, it was Jules who had to provide outrageous legal blags to put them off the trail. Judge Jules sounded appropriate, so the name stuck and thus Judge Jules DJ career was born.

Jules got into the House scene in 1986 and started traveling to New York to buy records and it was here he experienced the incredible atmosphere house music was producing. Although Jules was into the music before this, he had never experienced it in its full glory. As house turned to acid, he remained a prominent figure in the rave scene, playing at many of the legendary Orbital raves, including Energy, Back to the future and Sunrise. Together with his longtime friend Roy the Roach Jules started his prolific remixing career with a mix for the then Virgin Records based Bas' Noirs "Im Glad You Came", early remixes also included Soft House Company, Big Audio Dynamite and Fat Man.

Other notable remixes include T-Empos house classic 'Saturday night, Sunday morning', Josh Winks 'Higher State Of Consciousness', Ruffnecks 'Everybody Be somebody', plus the big money spinners Doop and Reel 2 Real (I like to move it), on the Positiva label.
