 Cristián Blasser and Mario Gutiérrez , students from the Escuela Consolidada de San Carlos ( now Liceo Politécnico de San Carlos ) , and Sergio Rojas , who worked at the school , formed a band in 1968 . Upon hearing an announcement of a bands tournament organized by La Discusión radio station from Chillán , they recruited Germaín de la Fuente , who was well known in the local scene for his vocal abilities . Blasser and Gutiérrez played the guitar , Rojas the bass , and De la Fuente became the keyboardist and lead vocalist . Most of the band members were musically inspired by acts such as The Beatles except De la Fuente , who did not like them at all and wanted to do bolero music . As a result , they created a mixed style known as the Balada rockmántica or Bolero @-@ beat .
