Argentine singer Mercedes Sosa performs Sept. 1, 2007 in La Plata, Argentina, Mercedes Sosa still has that incredibly powerful voice, lyrical, earthy and borne of 70s protest songs when jackboot military dictatorships held sway across South America. In an interview with The Associated Press, Sosa talks about her detention under military rule, her forced exile, and her worldwide travels to carry Argentina's protest songs and folk beats to concert halls from New York and London and beyond.
