Argentinean folk-rock band Sui Generis was formed in the early ’70s 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. Due to internal discrepancies, the group decided to perform for the last time at Buenos Aires’ Luna Park on September 5, 1975. That farewell concert was recorded and later issued as Adiós A Sui Generis, a double album and documentary considered to be a major event in the Latin rock history. The band reunited in 1980 to play shows in Montevideo, Uruguay, and Santiago de Chile. In the year 2000, Sui Generis returned with Sinfonía Para Adolescentes and an American tour.
