Quarteto 004 emerged in the late 1960s as a Brazilian vocal ensemble deeply influenced by the bossa nova movement. Their sole album, "Retrato em Branco e Preto" (1968), showcases collaborations with luminaries like Antônio Carlos Jobim, who contributed arrangements and performances, and Eumir Deodato. The group's harmonious vocals and sophisticated arrangements reflect the era's rich musical tapestry, leaving a lasting imprint on Brazil's popular music scene.
