Kortatu was a ska punk band from the Basque Country formed in Irun in the summer of 1984. Kortatu was born in the context of the first democracy years in Spain in 1984. They had a big significance for left-wing basque nationalism (which rejected the new constitutional project) as precursors of a new wave of music: Basque Radical Rock (Rock Radikal Vasco or RRV in Spanish).
