The song most remembered from that album was La rubia tarada, which was previously called Una noche en New York City. The lyrics of Mejor no hablar (de ciertas cosas) were written by Indio Solari, a guy who already had experience with rock. The story of that song began in 1982, when Redonditos de Ricota invited them to play at a festival. Solari didn't want to perform in a daytime place, so he stayed in the audience. Prodan played the whole show at that moment. Later, during rehearsal, he noticed that slow song the band was playing without a plan. He told Arnedo to speed up the bass, and thus the song transformed.
The album also includes other tracks that marked the voice of Sumo, such as No acabes or El reggae de paz y amor, which are examples of how they mixed rock with reggae sounds that had never been heard before in Argentina. The sound was taken care of by Luis Brozzoni, and the photos were taken by Max Stuart, from Australia. It was an album that put them on the map, without needing anything else.
