Gal Costa and Caetano Veloso debuted in the music industry in 1965, recording a single each, when Joao Araújo, director of Philips (Universal Music) record label, decided to launch an album with the two young artists together. Dori Caymmi produced and wrote some of the arrangements, alongside with Francis Hime and Roberto Menescal. Although the bossa nova influence is noticeable in the sound and performances of Gal and Caetano, fans of Joao Gilberto, the repertoire of 'Domingo' is written by composers of a new generation who disseminated their compositions at song festivals.
