Roots of Pescado Rabioso

Los Abuelos de la Nada were an Argentine rock band formed in Buenos Aires in 1967. The group underwent several incarnations throughout its history, with all of them led by its founder and frontman, singer-songwriter Miguel Abuelo. The group produced numerous hit singles in the 1980s as "Sin Gamulán", "Costumbres argentinas", "Mil horas", "Himno de mi corazón", "Lunes por la madrugada" and "No te enamores nunca de aquel marinero bengalí".

Almendra was an Argentine Rock band from Buenos Aires, Argentina. Led by guitarist and lyricist Luis Alberto Spinetta, Almendra released between 1968 and 1971 a few singles and two albums – Almendra and Almendra II – that revolutionized the sound of Argentine rock for the remainder of the 20th century and almost single-handedly changed the way local rock music was perceived by critics and audiences. Widely compared to The Beatles by their local contemporaries, Almendra did not survive the 1960s and the making of a planned rock opera, though all individual members went on to form the backbone of Argentine rock in the 1970s.
