El Cuarteto de Nos is an Uruguayan alternative rock band formed in 1984 in Montevideo. The band was originally comprised of the Musso brothers (Roberto and Riki Musso) and Santiago Tavella, who they had met in high school. In 1984 they released their debut album, a split LP with uruguayan candombe musician Alberto Wolf under the Ayuí / Tacuabé label. Leonardo Baroncini was hired to be a guest drummer on the record. In March 1987 they released Soy una arveja, an album which unlike their previous record featured dark, humorous and satirical lyrics based around characters from the city of Tajo, a fictional city (an inside-joke between the members).
