The story behind
Soda Stereo played Signos as a single in 1986, along with the album of the same name. The song began with an acoustic guitar riff, delay effects and synthesizers, creating a mysterious atmosphere. Then came the piano and the other instruments. Gustavo Cerati played the guitar, Zeta the bass and Charly the drums.
During the Ruido Blanco tour, they played it with two guitars and without bass. In 1988, during a show in Mala Noche No, Cerati used an electric guitar. Between 1992 and 1993, in Dynamo, the version changed with more effects and sampling. In the last concert, they performed it with accordion, keyboards and a more rock style. The 2007 version kept the original skeleton but with more modern sounds.
