Musically, the album revisits the alternative rock and pop foundations the band had been exploring, but with a more polished production and a melodic approach that allowed it to reach a wider audience. The lyrics, mostly the work of Roberto Musso, feature unique characters and uncommon situations, acting as a distorted mirror of reality. This combination of social criticism and entertainment became a trademark of the group. Among the most remembered songs that are now a fundamental part of their repertoire are «Bo cartero», «Sólo un rumor», and «El putón del barrio». Sales were notable for a Uruguayan rock band of that era, and this allowed them to perform on many stages across the country.
The history of El Cuarteto de Nos dates back to 1980, when they started as a group that performed covers of other artists, during the military dictatorship in Uruguay. At the end of that period, in 1984, they released a work with Alberto Wolf, which included performances at the Teatro El Tinglado. By 1987, with their second album Soy una arveja, they debuted in costume at the Teatro El Galpón. In 1985, they had already caught the attention of young audiences with striking outfits. Around that time, they were considered one of the most promising post-dictatorship rock bands in Uruguay, even participating in the massive Montevideo Rock event. After Emilio García in 1988, they performed under parodic pseudonyms. In 1991, during the recording of Canciones del corazón, keyboardist Andrés Bedó left the group. This album, released only on cassette due to the limitations of the Orfeo label, was a point of friction, as the band sought to release it in compact disc format. Faced with the label's refusal, they negotiated with the independent Ayuí / Tacuabé. The latter, although initially hesitant due to the underground context, agreed to release the first Uruguayan rock album on CD (also on cassette) after a profit-sharing agreement.
