In 1959, Astor Piazzolla was on a tour of Spanish-speaking America when, during a presentation in Puerto Rico with
Juan Carlos Copes and Maria Nieves Rego, he received news of the death of his father, Vicente Piazzolla, nicknamed Nonino, due to a bicycle accident in his hometown of Mar del Plata, Argentina. This news, coupled with the tour's failure, economic problems and homesickness, led Piazzolla to depression. After receiving such devastating news he composed this work in about 30 minutes as a tribute to his father, based on "Nonino", another tango Astor had composed five years earlier in
Paris, France, also dedicated to Vicente Piazzolla. == Background ==
