Mercedes Sosa, known as 'The Voice of America', was a singer of Argentine folk music well known throughout Latin America and internationally. She was born on July 9, 1935, in Tucuman of Mestizo, French and Quechua Ancestry. Mercedes is considered the founder of the New Song movement. She defined herself as "Cantora" instead of a "Cantante" (both words translate to "singer" in English), which was the defining element of the Latin American "nueva cancion". "Cantante" is one who CAN sing, but "cantor" is one who MUST sing. Mercedes was best known as the "voice of the voiceless ones".
