In 1991, with the alternative "Alerce" music label, Los Tres recorded their first album, Los Tres. Despite being only a moderately successful album with songs that mixed Rock, Jazz, and Blues, "Los Tres" nevertheless became an important album in the early nineties. The single "Un Amor Violento", and its low-budget music video became very popular in Chile. The lyrics in some songs of this album (like in "La Primera Vez" and "Flores Secas") talk strongly about their opposition to the Pinochet coup and the human rights abuses during the military regime.
