Argentinean folk-rock band Sui Generis was formed in Buenos Aires, Argentina in 1971 by singer, guitarist, and keyboardist Charly García and singer/instrumentalist Nito Mestre, who met while being high school students. Their first record, called Vida, was released in 1972, followed by 1973's Confesiones de Invierno. The following year, bassist Rinaldo Rafanelli and drummer Juan Rodríguez joined the act, soon recording Pequeñas Anécdotas Sobre Las Instituciones.
