A charming computer-generated character, Bartolo, discovers music as a prehistoric human, listening to the bird, and then perfects his art through the centuries before the arrival of Spain. The works of Bach and Mozart echo the earlier discoveries. A translation of Barroco (1989) into the language of educational animation allows Leduc (with the help of the music by Héctor Infanzón), according to film historian Roseli Rojo Posada, to represent Latin America as a diverse and complex territory and to propose its counter-history, based on the knowledge of the Indigenous communities.
