In 1969, a group of young people from the San Martín department (Moyobamba), in eastern Peru, under the direction of Jorge Rodríguez Grández, decided to form a musical group with which they sought to spread the music and customs of their native region; they adopted the name Los Saetas. They were the brothers Jorge and Carlos Rodríguez Grández, who to the sound of guitars and accordion brought life to the festivities in their homeland.
In 1971, they arrived in Lima, loaded with instruments and many dreams of conquering the Capital City. In this year, the last Rodríguez Grández brother, Segundo, joined the group, as well as their cousin Wagner Grández. It is also in this year that they decided to change the name of the group to Los Mirlos, in honor of the small black bird typical of the Peruvian Amazon.
Los Mirlos continue to perform nationwide, always with resounding success. They already have almost 30 albums to their credit, between LPs and CDs, featuring an enormous quality of songs not only instrumental, but also many of them sung.
Many of their songs achieved great acceptance in other Latin American countries, such as in Argentina, where the group Damas Gratis has within its repertoire songs like La Danza de los Mirlos and El Lamento de la Selva.
Among the hits of Los Charapas de Oro, precursors of Amazonian cumbia, and the so-called Poder Verde, we find many that are already true cumbia anthems not only of the east, but of the entire Peruvian territory. .
