Judge Jules (aka Julius O'Riordan) is a house and progressive trance DJ/producer from the UK. Choosing his alias as a reference to his law studies in London, Judge Jules began DJing professionally around 1987 and soon started hosting popular electronic dance music-oriented radio shows throughout England. His most popular program, "The Weekend Warm-Up," has been a house and trance institution on Radio 1 since late 1997 and has served as a tastemaker of sorts for the two wildly popular dance genres. In addition to all of this, Judge Jules hosts a regular dance night in Ibiza, has served as a music journalist and even has his own clothing line.
