2011 collection from the Argentinean vocalist. Considered by many to be the most important singer ever to come from Argentina, Mercedes Sosa released 70 albums in a remarkable career that spanned over half a century. A founding member and driving force behind the Neuva Cancion movement, Sosa sang with a contralto voice of extraordinary depth and beauty. Her interpretation of songs by icons such as Atahualpa Yupanqui and Violeta Parra helped popularize the movement worldwide. Sosa's political stance earned her a reputation as 'the voice of the silent majority' and ultimately led to many years living in exile away from military rule in Argentina. Her return to her homeland in 1982 after a decade away was triumphant and many huge selling albums were to follow, as well as World tours, Latin Grammy Awards and further acclaim. Wrasse.
