Sosa may refer to:

Haydée Mercedes Sosa (9 July 1935 – 4 October 2009), known as La Negra (literally: The Black One), was an Argentine singer who was popular throughout South America and many countries outside the continent. 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.

Sosa was born on 9 July 1935, in San Miguel de Tucumán, in the northwestern Argentine province of Tucumán, of mestizo, French, and Quechua Amerindian ancestry. 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 scene while seating among the public by fellow folk singer Jorge Cafrune-, brought her to the attention of her native countrypeople.

Milton Nascimento (Portuguese pronunciation: [miwˈtõ nasiˈmẽtu]; born October 26, 1942, Rio de Janeiro, Brazil) is a prominent Brazilian singer-songwriter and guitarist.

Nascimento's mother was the maid Maria Nascimento. As a baby, Milton Nascimento was adopted by his mother's former employers: the couple Josino Brito Campos, a banker employee, mathematics teacher and electronic technician; and Lília Silva Campos, a music teacher and choir singer. When he was 18 months old, Nascimento's biological mother died, and he moved with his adopted parents to the city of Três Pontas, in the state of Minas Gerais.

Nascimento was an occasional DJ on a radio station that his father once ran. He lived in the boroughs of Laranjeiras and Tijuca in Rio de Janeiro.

In the early stages of his career, Nascimento played in two samba groups: Evolussamba and Sambacana. In 1963, he moved to Belo Horizonte, where his friendship with Lô Borges led to the Clube da Esquina ("corner club") movement. Members included Beto Guedes, Toninho Horta, Wagner Tiso, and Flávio Venturini, with whom he shared compositions and melodies. One composition was "Canção do Sal", which was first interpreted by Elis Regina in 1966 and led to a television appearance with Nascimento. The collective, as well as some others, released Clube da Esquina in 1972. Several hit singles were also released.

Gal Costa (born Maria da Graça Costa Penna Burgos on September 26, 1945, in Salvador, Bahia) is a Brazilian singer of popular music.

Gal Costa was born on September 26, 1945, in the city of Salvador, the state capital of the state of Bahia, Brazil. Her mother, Mariah Costa Penna (deceased 1993) spent hours listening to classical music during her pregnancy in hopes that Gal would be interested in music. Gal's father, Arnaldo Burgos (deceased 1960), died when Gal was 15 years old and the two would never meet.

At the age of 10, Gal befriended sisters, Sandra and Andréia Gadelha, the future spouses of singer-songwriters Gilberto Gil and Caetano Veloso, respectively. At 14, she first listened to João Gilberto's "Chega de Saudade" on the radio and became interested in Bossa Nova. She then went on to work as a clerk on Salvador's main record store to get closer to music. At 18, she was introduced to Caetano Veloso by Andréa Gadelha, engaging with him in a deep friendship that still lasts.

Costa debuted her professional career on the night of August 22, 1964 on the concert Nós, por exemplo, where she performed alongside Veloso, Gil, Maria Bethânia and Tom Zé, among others. The concert inaugurated the Vila Velha Theatre in her hometown. During the same year, she also performed in Nova Bossa Velha, Velha Bossa Nova, at the same place and with the same singing partners. She then left Salvador to live in the house of her cousin Nívea in Rio de Janeiro, following the footsteps of Bethânia, whose concert, Opinião, had become a huge hit on the town.

Julio María Sosa Venturini (February 2, 1926 – November 26, 1964), usually referred to simply as Julio Sosa or El Varón del Tango, was an Uruguayan tango singer.

Sosa was born in Las Piedras, a Canelones Department suburb of Montevideo, Uruguay. He moved to Buenos Aires, Argentina, in 1949, where he became famous with the Orquesta Francini-Pontier the Orquesta típica formed by the violinist Enrique Mario Francini and the bandoneonist Armando Pontier . Working with numerous other orchestras, he was reunited with Pontier in 1955, with whom he recorded several best-selling albums on the RCA Victor and Columbia labels and became one of the most important tango singers in the genre's history.

He married Nora Ulfed in 1958 and had a daughter. His marriage ended in separation, however, and he settled into a relationship with Susana Merighi. Nicknamed El Varón del Tango ("the man's man of tango"), Sosa also published a book of poetry, Dos horas antes del alba ("Two Hours Before the Dawn"), in 1960. Following his switch to Columbia Records in 1961, the Pontier orchestra incorporated a new bandoneonist, Leopoldo Federico, and the association helped make the group the most successful in its genre, at the time.
