Mapuche language
Quilapayún originated in 1965 when Julio Numhauser and the brothers Julio and Eduardo Carrasco formed a folk music trio, which they simply called "the three bearded men" (viz. "Quila-Payún") in the Mapuche language (viz. Mapudungun – the language of the people native to the region that is now the south of Chile, the Araucanians).
