On the centenary of the birth of Astor Piazzolla (1921-1992), this book traces the biographical and artistic events that led the great Argentine composer to the creation of Nuevo Tango. Following a precise and detailed chronology, the most significant works of each phase of his glittering career are suggested to the listener: contaminations between genres, collaborations with the great protagonists of jazz, film productions, concert music, songs, poetry, and dance. The treatment is accompanied by an annotated and complete discography, in which Piazzolla figures both as a composer and as an interpreter. Finally, a chapter is dedicated to the fortune of his music from his death to the present day: protagonist of the most important international concert seasons, loved and performed by the greatest interpreters, acclaimed and requested by audiences all over the world. Preface by Laura Escalada Piazzolla and Daniel Villaflor Piazzolla.
