Real name: Dossier Negro

Spanish band formed at the beginning of the eighties, after the dissolution of Borne, composed by José Miguel Oca (voice and bass) and Sergio Oca (drums and drum machine). Juan Manuel Martínez "Juanma" joins them as guitarist.
In 1984 he recorded a single 'No hay color / Paseando', edited by DNI and with the collaboration of Ricardo Ravet (Blanco I Negro) to the keyboards.
Two years later, in 1986, they decided to shorten their name to stay with only Dossier.
