The choral group was formed in September, 1980 at the initiative of Fray José Luis Estalayo de Mier, a Franciscan priest from Spain who carried out parish activities in the city of Huaraz.
For the selection process, dozens of children from the parish of Huaraz arose, and finally were chosen Miguel Villarreal, Manuel Collazos, Julio Cesar Campos, Elisa Machuca de Winter and Melina Carrillo, children who had between nine and eleven years old, all of them students of the College National parish Santa Rosa de Viterbo of urbanization La Soledad, in the city of Huaraz in Peru.
They were to the city of Lima, made several music tests and signed with the label Industrias Electricas Y Musicales Peruanas, IEMPSA to sing some Christmas carols to rhythm of Cumbia, except one that was composed by Fray José Luis Estalayo de Mier to rhythm of Rumba.
As part of its production, was launched to the local market a Christmas carols album with the name of "Los Niños Cantores de Huaraz - Villancicos En Cumbia" (Children singers of Huaraz) and few time after lauched another album, "Te Invito A Mi Fiesta" (I Invite You To My Party) which sold more than 5,000 copies.
LPs of this choral group were sold also in Ecuador, Colombia, Venezuela and Argentina.
They had previously recorded a single called "Mensaje De Paz" (Message Of Peace) that was broadcast on TV program "Trescientos Millones" (300 million in Spanish) that served as the background music of a Christmas special performed on Channel 7 in the Peru of the '80s.
Their music and performances may be heard until today. One of the secrets of their success were the daily trials after school classes, which brought them even to participate in a special of Channel 4 of Peruvian TV, specifically in the children's program called "Tio Johnny", a famous television broadcast at national level in Peru.
