Oscar began his career in the late 80's in Madrid playing EBM and Gothic Rock, the dominant styles of the time. He entered the limelight when he set up the legendary club, The Omen in the early 90's, a club, which quickly became the focus for hypnotic dance music in Spain. The closure of The Omen in 1995 marked a change of direction in Oscar’s career. He began play all round Spain and gradually distanced himself from the trancy lysergic sound he had previously favoured and moved towards the more basic minimal techno influenced by artists such Joey Beltram and the new Detroit sounds of Jeff Mills.

By this time he had become icon in his home country and the maximum exponent of the hard techno sound in Spain, his popularity grew in an unstoppable geometric progression. Oscar’s sound became more and more focused, incorporating techno's most forward looking developments into his sets. His incredible skills behind the decks and spectacular EQ techniques never leave the crowd indifferent. Oscar has released two CD mixes to date. The first About Discipline and Education (So Dens, 1998) showcases the latest sounds personified by Surgeon, Ho, Polson and Ruskin alongside some classics of Hard Techno. His second mix Era (Rexxistance, 2000) brings together the most advanced sounds ranging from Autechre through to the essentials from Ho, Ruskin, Surgeon and Mulero himself.

While his Dj schedule took him round the world, Oscar started producing and released his first record, Quite Inusual on his Madrid label Brainwaves. In 2000 Oscar set up his own label Warm Up and began to focus on his studio work. The first two releases Medical Mesh and Sans Souci went down well and were included in the Top 10’s of artists such as Surgeon and Ben Sims. Since then he has gone on to record prolifically for well known international labels including Theory. Oscar has also released Indoor Culture Remixes and Trolley Route; a melodic Detroit influenced 3 track EP on the British label Pure Plastic. On the same label and in the same style he has also released Occhi Chiusi, the first Trolley Route LP that includes remixes by other artists such as Robert Hood and Steve Rachmad. The Trolley Route sound is also designed for home listening not purely for the dancefloor

Oscar’s experimental tendencies and his desire to explore have led him to champion other styles outside the confines of techno such as electro and drum and bass. He forms part of the Dark Archives Collective alongside Dj Pitch, Focus and Dj Muerto running Altered State, the first club in Madrid to promote the drum and bass sound and one of the most underground and futuristic in the capital.

Twelve years experience in the world of techno, his charisma and his professionalism have turned Oscar into something more than just a DJ. Oscar is admired wherever he goes and nobody can deny his status in the Spanish techno scene. However what is truly remarkable is that all his success has come from the things he most identifies himself with: hope, dedication and one hundred per cent passion for his work.
