Jorge Antonio Cafrune (Jujuy , August 8th 1937 - Buenos Aires , February 1st 1978 ) was a one of the most popular Argentinian folklorist singers of his time, aside from being an unflagging investigator, compiler and diffuser of the native culture. Jorge Cafrune was born in the estancia "La Matilde" of El Sunchal , Perico Del Carmén , Jujuy . He completed his secondary studies in San Salvador de Jujuy, during which he took guitar classes with Nicolas Lamadrid. In 1957 he recorded his first disk with the band Las voces de Huayra that in 1960 changed its name to Los cantores del Alba, with Ariel Ramirez as manager. Beginning in 1962 , Cafrune began to perform at the Cosquin Folkloric Festival . In 1966 in one of his visits to smaller villages, he met a young folklorist singer named José Larralde . In 1967 shown the trip "De caballo por mi patria" in homage to Chacho Peñaloza . During this trip Cafrune traveled about Argentina as had many gauchos, taking his art and message around the country. In 1977, after several years spent living in Spain, he returned to his country. Times were difficult for the Argentine, as the government was under the restrictive military dictatorship of Jorge Rafael Videla . The government saw a menace in Cafrune's outspoken music, and in particular one politically controversial song of his, "Zamba de mi esperanza". On his persistence, Cafrune said, "Although it is not in the authorized repertoire, if my people request it of me, I am going to sing it." On January 31th of 1978, Lieutenant Colonel Carlos Enrique Villanueva ordered the assassination of Cafrune. After being run over by a van driven by two nineteen year old men, Cafrune died within twelve hours.
