The Power of Their Song is a 90-minute documentary film (currently in production) about beloved, Latin American folk-based musicians, most notably Victor Jara, who sang moving songs of freedom during times of dictatorship. Their powerful songs, composed largely during the 1960's and 1970's, blend beautiful, and at times haunting, melodies with passionate and poetic lyrics expressing the hopes and fears of a generation of Latin Americans. Known as Nueva Cancion, or New Song, this tradition of rural, folkloric music has continued to evolve, absorbing many different regional influences and taking on new creative forms. Well-known musicians from around the world have covered some songs in the tradition. Using interviews to be filmed across South and Central America, the film will document the remaining major artists of this period, including: Roy Brown of Puerto Rico, Daniel Viglietti of Uruguay, Silvio Rodriguez of Cuba, Leon Gieco and Mercedes Sosa of Argentina, Chico Buarque of Brazil, Gabino Palomares of Mexico, as well as musicians from Venezuela, Nicaragua and other Latin American countries.
