Watch VoirFilms. An exploration of the Latin American protest song through performances and interventions by some of its most prominent figures: Pablo Milanés, Lilia Vera, Mercedes Sosa, Joan Manuel Serrat, Daniel Viglietti, Carlos Puebla, Sara González, and Gloria Martín. Filmed on the occasion of a concert organized by the University of the Andes at the Mérida Bullring, the documentary constitutes an essential record of the Nueva Canción movement as a continental cultural force within the broader context of the political struggles of its time.
