"Noche De Perros" comes from the Argentine rock supergroup Serú Girán, a band celebrated for its musical and conceptual depth within rock en español. The group formed in 1978, bringing together established musicians like Charly García and David Lebón, who had traveled to Brazil to write songs for a new album, and later joined by the talented Pedro Aznar and Oscar Moro. Appearing on the 1979 release "La grasa de las capitales," the song emerges from a rich musical lineage, reflecting the collaborative spirit of these influential artists. Playing it might evoke the nocturnal introspection suggested by its title.
