Rock was not that popular with the youth of Latin America (with the exceptions of Argentina and Uruguay) and bands were not accustomed to international tours. On 10 November 1986 the band released their third album Signos. With its lead single "Persiana Americana" (:es) (American Blinds), Signos was a key step for Soda Stereo, who by now had come under a great deal of stress due to ever increasing factors: sales expectations, external pressures, the risk of failure, and internal tensions. The band was joined in the studio by on keys, Richard Coleman on guitar and on back up vocals. Signos became the first Argentine rock album to be released on compact disc. It was manufactured in the Netherlands and distributed throughout Latin America. On 3 December Soda made their first appearance in Ecuador. In early 1987 Soda returned to Chile, this time to the Viña del Mar International Song Festival where they won the prize "Antorcha de Plata" (Silver Torch).

With live recordings from different shows, a live album Ruido Blanco was compiled in 1987. Mixed in Barbados, it was considered by Rolling Stone (Argentina) to be one of the top 5 live albums of Argentine Rock. In late 1988 Soda Stereo were considered the most important band of Latin American pop/rock. They began to work on a new album alongside Puerto Rican producer Carlos Alomar. Alomar had worked with David Bowie, Mick Jagger, Simple Minds, Iggy Pop, and Paul McCartney, among others. Doble Vida (Double Life) was recorded and mixed in New York City, and was the first record by an Argentine band to
