In 1978, the members of the band Indar Trabes prepare to release an LP for Durango's Basque book and music fair, including songs composed largely by frontman and central figure Juan Carlos Perez. They decide to rebrand the group on the grounds that the previous name was associated to evening dancing performances. They chose Itoiz, because it is brief, not because of the famous valley of the same name in Navarre. This first album features intimate and whimsical lyrics, difficult to understand, wrapped up in progressive rock music.
