In 1991 they released their first album entitled "Fabrico cuero" (I make leather), which combines rap, synthesized sounds, catchy melodies and ironic lyrics. Although some in the media initially suggested their popularity came from their family connections rather than their musical skills, that changed when Charly García invited them to play at one of his shows to perform "Fabrico cuero" and "Rap del exilio". They shared the stage with Luis Alberto Spinetta in Venezuela. In 1991 they were voted as la Revelación ("best newcomers") in the newspaper "Clarín".
