With her powerful voice and compelling stage presence, the Argentine folk singer, Mercedes Sosa, was a world-class performer, whose influence went far beyond the borders of music. Blacklisted as being one the most dangerous people to the regime in Argentina in the 1970s, she became the underground reference point for the poor and oppressed, and an icon of democracy who fought South America's dictators with her voice.

Alongside her lifelong career, which earned her four Grammy Awards, Sosa also worked as Goodwill Ambassador for the children in Latin America and in the Caribbean, and was granted the prestigious position of Vice President of the Earth Council.
