The first name was "Cicatriz en la Matriz", which included Natxo Etxebarrieta and his girlfriend Poti, together with Pescadilla on bass, Pedro Landatxe on the drums and Pepin Arteaga on guitar.

The group is consolidated with Natxo and Poti as the singers, and this line-up recorded a demo in Pamplona, in 1984, with the songs "Botes de humo" (Tear gas), "Cuidado burócratas" (Beware, bureaucrats) and "Aprieta el gatillo" (Pull the trigger).

By 1986, the band released its first LP Inadaptados ("Misfits"), recorded at Elkar (Lasarte) Studios, with Jean Phocas as engineer and Josu Zabala (leader of Hertzainak) as producer.

His replacement was Goar Iñurrieta (member from the hard rock bands Bizkar Hezurra and Korroskada) and continued performing shows to 1988, where Natxo is arrested in Barajas, on charges of drug traffic from the Netherlands, to find a package of amphetamine pills in his luggage.

Then, Natxo and Goar continued with the group with Diego "Dieguillo" Garay (former Quemando Ruedas bass guitar) and Pedro Fernández Iradier (Rock DAM drummer) as replacements, recording the live album En Directo.
