Hailing from Perpignan, a town in the south of France, Guillaume became involved in the electronic music movement in 1994. He began his DJ career earlier the same year, attracting promoters’ attention and playing not only in the Perpignan area, but also in the north of Spain. Falling in love with Spain, in 1995 he decided to try his luck and develop a career there. Little by little, he would become the resident DJ of the 'Corto Maltese' club in Besalú (Northern Spain) and Komix in Olot. From 1997 on, GuyOhm appeared in renowned Spanish clubs such as 'La Cova / Barcelona', 'Blau / Girona', 'Nan / Granollers', 'Liquid Sky / Figueres', 'Palm Beach Club' / Sant Feliu de Guixols', 'Cyberian / Barcelona', 'B: Side / Malgrat de Mar' and French clubs such as 'LR / Toulouse', 'Aposia / Toulouse', 'Marina Atlantide / Barcares'. He also had the opportunity to share booth with international DJs such as Luke Slater, Oxia, J.Rob, Oliver Lieb, Francesco Farfa, Roland Casper, Colin Dale, Paul Kalkbrenner, Kiko, Trentemoeller ... to name a few.
A great lover of music in every way, this great character of the electronic scene has one desire: taking his public on a trip, guiding them to a state of total euphoria. And he means it: GuyOhm has been able to play for up to 20 hours in a row. With a musical style that has always followed the trends and mastering his technique perfectly, he knows how to adapt without any difficulty to his dancefloor.
In 2002, he joined the booking agency 'Affinity Management' and released his first album with J-Rob on the label 'Energy Base'.
In 2004, GuyOhm opened the record store "Vinylothèque" with his partner Laetitia in Girona, offering services to DJs and producers.
In 2007, he inaugurated his own DJ & Music Production School "Studiotech", also in Girona. On the same year, he created Menosmal Recordings with David Monje, a label releasing electronic music in both physical and digital formats.
Since 2017 GuyOhm lives and works in Berlin, Germany.
