Serú Girán was an Argentine rock supergroup. Formed in 1978, the group consisted of Charly García (keyboards, synthesizers and vocals), David Lebón (guitars and vocals), Oscar Moro (drums and percussion) and Pedro Aznar (electric and fretless bass and vocals) the three first being already consecrated musicians through their previous bands. It is considered one of the best in the history of rock en español, both musically and conceptually, including the staging
Serú Girán was born after the separation of the band La Máquina de Hacer Pájaros which Charly García had organized in his early post-Sui Generis. Along with David Lebón, Charly García traveled to Búzios (Brazil) in 1978, with the idea of writing songs for a new album. On their return to Buenos Aires, García met the young and talented bass player Pedro Aznar. They were then joined by Oscar Moro, who was the drummer of La Máquina de Hacer Pájaros and formerly of the legendary group Los Gatos.
