[3] Bassist Santiago Tavella was recruited as a long-time friend who, just like them, was an enormous fan of artists like The Beatles, Bob Dylan and Led Zeppelin.

In 1985, they stepped on a stage, located in a fair from Villa Biarritz, dressed up with aluminum foil on their legs and balloons tied to their heads.

[5] The following year, band members dressed up as elderly women to promote the song "Soy una Vieja" (transl.

[6] Soy una Arveja incorporated more electric guitars and surreal lyrics than in their album with Wolf, with many elements of new wave and Avant-garde music.

They made references to the fictional city of Tajo and used their characters to apply a comedic or humorous lens on serious topics, such as sex, greed, and death.

In 1994, after four years of working on new songs, they released their album Otra Navidad en las Trincheras (transl.

This album was controversial in Uruguay, since one of its songs, "El día que Artigas se emborrachó" (transl.

El Cuarteto de Nos released Raro (strange or weird in English) on May 20, 2006, as a departure from their previous work.

[10] The band promoted their new album at several latin american stages such as Rock al Parque 2007 in Bogotá, Colombia [11] and the Pepsi Music 2008 festival in Buenos Aires, Argentina.

[13][14][15] Raro and the rest of the trilogy marked a turning point for the band, leading to a surge in popularity in South America.

Throughout the trilogy, Tavella would sing the lead vocals on two tracks on each album, serving as a break that juxtaposed Roberto Musso's fast and energetic lyrics.

On May 27, 2009, in the midst of the development of their album Bipolar, it was reported that Ricardo Musso had artistic and administrative differences with the course the band had taken.

It was particularly personal for vocalist Roberto Musso, touching on his family history of Alzeheimers, how to quell a child's fears, and self-doubt.

There were many producers on the album: Juan Campodónico (Raro and others), Eduardo Cabra (Calle 13), Héctor Castillo (No Te Va Gustar), and Camilo Lara.
