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.

Francisco Buarque de Hollanda (born June 19, 1944 in Rio de Janeiro, Brazil), popularly known as Chico Buarque (Portuguese pronunciation: [ˈʃikʊ ˈbwaɾkɪ]), is a singer, guitarist, composer, dramatist, writer and poet. He is best known for his music, which often includes social, economic and cultural commentary on Brazil and Rio de Janeiro in particular.

Son of the academic Sérgio Buarque de Hollanda, Buarque lived in several locations throughout his childhood, though mostly in Rio de Janeiro, São Paulo and Italy. He wrote and studied literature as a child and came to music through the bossa nova compositions of João Gilberto. He performed music throughout the 1960s as well as writing a play that was deemed dangerous by the Brazilian military dictatorship of the time. Buarque, along with several of his fellow musicians, were threatened by the government and eventually left Brazil in 1970. He moved to Italy again. However, he came back to Brazil in 1971, one year before the others, and continued to record albums, perform, and write, though much of his material was not allowed by government censors. He released several more albums in the 1980s and published three novels in the 1990s and 2000s, all of which were acclaimed critically.
