Carlos Ruiz, a.k.a. Dj Voltteretto started to work like disc jockey in one of the finest & famous dancefloors in Madrid since 1988. Cult formations like Leæther Strip, Pankow, Front Line Assembly, Skinny Puppy, Infact, Click Click or The Klinik are only some referencies that later will influence him. A strange day at 1998, happened a lucky strike, Carlos met Marcos during a hard and severe EBM/Industrial session. So, was born Dioxyde.
