Luz Y Sombra

The promotion of this album began in July 1987 with the release of the single "Corre, Corre", but during the months of August to October developed a campaign for the benefit of the victims of Tlatelolco, for the reconstruction of this housing complex after the earthquake of September 19, 1985. This was the response to the pressure exerted by the organization of the residents of Tlatelolco who demanded democratic participation in the face of emergency conditions, which abruptly manifested an accelerated expression of long-standing ruptures between the State and the middle classes of Mexican society. In this campaign Flans participated with the song with lyrics, music and arrangements by Amparo Rubín. This 2:45 song featured a video clip produced and directed by, which was filmed at the Plaza de las Tres Culturas in Tlatelolco, Mexico City. The broadcasting of this video clip was also used for the release of this album on September 19, 1987 in commemoration of the earthquake that occurred in Mexico City two years earlier on the same date, and that by 1987 the community of Tlatelolco was still suffering its consequences.
