Adieu... 

Quizás, las palabras de su entrañable amiga, Teresa Parodi, resuman el sentimiento de muchos:

“…Mercedes, salmo en los labios
amorosa madre amada
mujer de América herida
tu canción nos pone alas y hace que la patria toda
menudita y desolada no se muera todavía,
no se muera porque siempre cantarás en nuestras almas…”

Dear Mercedes
I grew up listening to your beautiful voice and learning about great and popular poets through your discography...
My eight years old son this morning said to me: "I do not know any other like her"... and he is right. No one like her...
We will miss you very much...
Mercedes Sosa - Gracias a La Vida

To all of you, who have no idea who this amazing artist is, or was…. I found this info I want to share:
Mercedes Sosa, known as La Negra, (July 9, 1935 – October 4, 2009) was an Argentine singer who was and remains immensely popular throughout Latin America and internationally. With her roots in Argentine folk music, Sosa became one of the preeminent exponents of nueva canción. She gave voice to songs written by both Brazilians and Cubans. She was best known as the “voice of the voiceless ones”.

Sosa performed in venues such as the Lincoln Center in New York City, the Théâtre Mogador in Paris and the Sistine Chapel in Vatican City, as well as sell-out shows in New York’s Carnegie Hall and the Roman Coliseum during her final decade of life. Her career spanned four decades and she has been the recipient of several Grammy awards and nominations, including three nominations which will be decided posthumously. She served as an ambassador for UNICEF.
