Release Signos' release date is unknown due to lack of documentation, it's estimated to have been released in November 1986. Bitar claims that it was released on the 10th, however Giordano disagrees and writes that it was released on the 3rd. It was originally released in the
LP and
cassette formats by
Columbia Records. Later, in March 1988 it was issued on the
CD format, becoming along with by Charly García one of the first Argentine albums to be released in the format. CDs of the album were fabricated in the Netherlands and distributed in
Latin America. Bolivian records were issued in the
EP format and only contained four songs: "Sin Sobresaltos", "No Existes", "Persiana Americana" and "Signos". Mexican records included text on the front cover reading "Incluye los exitos: "Persiana Americana", "Signos" y "Sin Sobresaltos"." (). For promotion, "Prófugos" was released as a single with "Signos" as the B side. "Persiana Americana" was released as the A side to "No Existes", and also released as the B side to "Sobredosis de TV", a song from
the first album of the band. No music videos were recorded for any of the songs in
Signos as they didn't have any time to do so.
Reception Initial reception With
Signos, critics started taking Soda Stereo seriously. ''
published its review of the album in January 1987, which they praised the more natural and soft sound featured in the album, describing it as shocking and a demonstration of quality. Rock & Pop'''s agreed in its review, also praising Cerati's poetic lyrics. She called the album a significant progress, pleasing both fans and those "who were once suspicious and distrustful of what was commercially easy". ''Pelo's
writer elaborates further and writes that Cerati treats guitars with a "very special maestry" and that he sings at his "very best". Soda Stereo had influenced new groups, which Pelo
mentioned, but with criticism writing that: "Unfortunately, their music has, in many cases, become a kind of model for those who seek a modern sound or simply want to live a success story". Bitar wrote in his review while working for magazine Canta Rock
in 1987, that Signos'' was the best album by the band and one of the best of previous years. Bitar also noticed a growth in Bosio as a bassist and praised Gowland's vocals in
El Rito and Quintero's playing in the title track. In 1986, surveys by both
Pelo and
Rock & Pop listed Soda Stereo as the best band, with the best album (
Signos), best song (
Prófugos), best performance and best singer (Cerati). Upon release, the album received a platinum certification in Argentina as 60,000 pre-orders were made before release. Which according to Columbia Records, was enough to cover the costs made during the making of the album. By 1987, it had sold 120,000 copies in Chile in the cassette format, 50,000 in the LP format, and had received two platinum certifications. Like Argentina and Chile, the album received a platinum certification in Perú, with 21,000 copies sold by 1987.
Retrospective reception In retrospect, Giordano wrote that
Signos started an evolution that ended with
Canción Animal (1990), which to him, placed Soda Stereo at the top of the history of
Rock en español. While authors Rubén Espejo and Eduardo Ortega write that it's one of the most important albums in the history of Rock en español.
AllMusic reviewer Adaime wrote in its 2001 review that the title track, Persiana Americana and Prófugos
allowed Soda Stereo to explore wider audiences and new musical directions. Daffunchio, later said in an interview about Persiana Americana'' that "The people turned ‘Persiana [Americana]’ into a success that no one imagined, not even Gustavo [Cerati]". Rolling Stone's Oscar Jalil described Cerati's
riffs in the album as one of his best as a guitarist. His magazine, Rolling Stone, ranked
Signos 25th on its list of "
The 100 Greatest Albums of Argentine Rock". == Track listing ==
