"El acordeon del Diablo" takes us to the Atlantic coast of Columbia, or more precisely Santa Marta, and portrays the life of Francisco "Pacho" Rada, composer and genial accordionist aged 93 and the same person who inspired in Gabriel Garcia Marquez the personality of the singer who confronts the devil in the musical duel, "One hundred years of solitude". In evoking this anecdote among many others which has since become classics of Latin American music, Rada is asserting that he has emerged unscathed from this duel, a victory worthy of saving his soul! Apart from the comments of Francisco "Pacho" Rada, other virtuosos of the accordion appear in this film, for example Israel Romero, current star of "paseo" or "vallenato", who accompanied by his nephew takes part in a mesmerising duo. An amazing journey composed of emphatic beliefs and intoxicating legends.
