She won the Premio Gardel in 2000, the main musical award in Argentina. She served as an ambassador for UNICEF.\\n\\n\\n== Life ==\\nSosa was born on 9 July 1935, in San Miguel de Tucumán, in the northwestern Argentine province of Tucumán, of mestizo ancestry. She was of French, Spanish and Diaguita descent. Her nickname \"la negra\", which is a common nickname in Argentina for people with darker complexion, is a reference to her indigenous heritage. Her parents, a day laborer and a washerwoman, were Peronists, although they never registered in the party, and she started her career as a singer for the Peronist Party in Tucuman under the name Gladys Osorio. In 1950, at age fifteen, she won a singing competition organized by a local radio station and was given a contract to perform for two months. She recorded her first album, La Voz de la Zafra, in 1959. A performance at the 1965 Cosquín National Folklore Festival—where she was introduced and brought to the stage while sitting in the audience by fellow folk singer Jorge Cafrune— brought her to the attention of the Argentine public. Sosa and her first husband, Manuel Oscar Matus, with whom she had one son, were key players in the mid-60s nueva canción movement (which was called nuevo cancionero in Argentina). Her second record was Canciones con Fundamento, a collection of Argentine folk songs.\\n\\nSosa \"spent the late 1960s building her audience in Europe and among the cosmopolitan middle class in Buenos Aires, becoming in the process a much bigger star\" than her contemporaries.In 1967, Sosa toured the United States and Europe with great success. In later years, she performed and recorded extensively, broadening her repertoire to include material from throughout Latin America.\\nIn the early 1970s, Sosa released two concept albums in collaboration with composer Ariel Ramírez and lyricist Félix Luna: Cantata Sudamericana and Mujeres Argentinas (Argentine Women). She also recorded a tribute to Chilean musician Violeta Parra in 1971, including what was to become one of Sosa\\'s signature songs, Gracias a la vida. She further popularized of songs written by Milton Nascimento of Brazil and Pablo Milanés and Silvio Rodríguez both from Cuba. Throughout the decade, she released albums such as Hasta la Victoria in 1972 and Traigo un Pueblo en mi Voz in 1973. They featured songs like \"Cuando tenga la tierra\", written by Ariel Petrocelli and Daniel Toro, which tackles political and social issues like wealth and land inequality. During the 1970s she was a part of two films by the director Leopoldo Torre Nilsson: El Santo de la Espada in 1970 and Güemes, la tierra en armas in 1971, in which she portrayed Juana Azurduy de Padilla, the guerrilla military leader who fought for Argentine independence.\\n\\nAfter the military junta of Jorge Videla came to power in 1976, the atmosphere in Argentina grew increasingly oppressive. Sosa faced death threats against both her and her family, but refused for many years to leave '),\n",

The variety of songs included range from songs performed with their original artist to songs performed with artists different than their original performer, many of the artists featured make reprises of their own songs for the album like Gustavo Cerati in the version of Soda Stereo\\'s \"Zonas de Promesas\", Charly García in the version of Serú Girán\\'s \"Desarma y Sangra\" and Luis Alberto Spinetta in the version of his song \"Barro Tal Vez\", while others appear in versions of songs not from their discography, like Shakira, who features in the track \"La Maza\", originally written and performed by Silvio Rodríguez, and Vicentico who appears the version of Ruben Blades\\'s \"Parao\". The albums end with a version of the Argentine National Anthem, being the only song in the albums to not feature a particular singer.\\n\\n\\n== Critical reception ==\\n\\nMariano Prunes from AllMusic gave both volumes of the album three and a half stars out of five. In his review for Cantora 1 he wrote that \"contrary to the quintessential Sosa recordings, Cantora is a fairly subdued affair, with most songs whispered against unobtrusive yet tasteful acoustic arrangements by Poppi Spatocco\", also commenting that the production \"certainly works very well, as it creates an encompassing sonic texture that helps to render the entire album less dissimilar than it may have been\". In the review for Cantora 2 he wrote that both albums as a whole are \"a touchi')]"
