In addition, González's acute social vision finds its place in "Las sierras eléctricas", with the romantic counterpart of "En forma de pez": a 7-minute suite inspired by Martin Gore from Depeche Mode.

[4] González left for Los Angeles, California in October 1989 with only the company of the band's manager, Carlos Fonseca, since Tapia was unable to obtain a visa to enter the United States.

Narea's departure was marked by the hidden relationship between his wife and Gonzalez, but he also had a musical artist: "He did not agree with the sound that the group's leader wanted to give the trio, influenced by synthesizers and electropop that unfolded in the '80."

All of their previous albums had been produced by González, however Santaolalla brought an "astounding new level of polish" to the band, infusing jagged electronic melodies with "soaring pop" production and regional instruments like the charango to solidify a sonic identity that was "originally and unquestionably Latin American".

Produced by Vicente Sanfuentes and Lego Mustache, the song "Estrechez de corazón" was covered by Carlos Cabezas, Francisca Valenzuela, and the group Villa Cariño.

In the tribute album to Jorge González, "Nada es para Siempre", the musicians Gepe and Javiera Mena, accompanied by Cecilia Aguayo, Uwe Schmidt, Felipe Carbone, and Gonzalo Yáñez performed a version of "Cuentame una historia original".
