Astor Piazzolla: Adios Nonino

the rest of the Piazzolla biography from wikipedia

With the composition of Adiós Nonino in 1959, Piazzolla established a standard structural pattern for his compositions, involving a formal pattern of fast-slow-fast-slow-coda, with the fast sections emphasizing gritty tango rhythms and harsh, angular melodic figures, and the slower sections usually making use of the string instrument in the group and/or Piazzolla's own bandoneon as lyrical soloists. The piano tends to be used throughout as a percussive rhythmic backbone, while the electric guitar either joins in this role or spins filigree improvisations; the double bass parts are usually of little interest, but provide an indispensable rugged thickness to the sound of the ensemble. The quintet of bandoneon, violin, piano, electric guitar and double bass was Piazzolla's preferred setup on two extended occasions during his career, and most critics consider it to be the most successful instrumentation for his works.[2] This is due partly to its great efficiency in terms of sound - it covers or imitates most sections of a symphony orchestra, including the percussion which is improvised by all players on the bodies of their instruments - and the strong expressive identity it permits each individual musician. With a style that is both rugged and intricate, such a setup augments the compositions' inherent characteristics.
Despite the prevalence of the quintet formation and the ABABC compositional structure, Piazzolla consistently experimented with other musical forms and instrumental combinations. In 1965 an album was released containing collaborations between Piazzolla and Jorge Luis Borges where Borges's poetry was narrated over very avant-garde music by Piazzolla including the use of dodecaphonic (twelve-tone) rows, free non-melodic improvisation on all instruments, and modal harmonies and scales.[3] In 1968 Piazzolla wrote and produced an "operita", María de Buenos Aires, that employed a larger ensemble including flute, percussion, multiple strings and three vocalists, and juxtaposed movements in Piazzolla's own style with several pastiche numbers ranging from waltz and hurdy-gurdy to a piano/narrator bar-room scena straight out of Casablanca.
By the 1970s Piazzolla was living in Rome, managed by the Italian agent Aldo Pagani, and exploring a leaner, more fluid musical style drawing on more jazz influence, and with simpler, more continuous forms. Pieces that exemplify this new direction include Libertango and most of the Suite Troileana, written in memory of the late Anibal Troilo. In the 1980s Piazzolla was rich enough, for the first time, to become relatively autonomous artistically, and wrote some of his most ambitious multi-movement works. These included Tango Suite for the virtuoso guitar duo Sergio and Odair Assad; Histoire du Tango, where a flutist and guitarist tell the history of tango in four chunks of music styled at thirty-year intervals; and La Camorra, a suite in three ten minute movements, inspired by the Neapolitan crime family and exploring symphonic concepts of large-scale form, thematic development, contrasts of texture and massive accumulations of ensemble sound. After making three albums in New York with the second quintet and producer Kip Hanrahan, two of which he described on separate occasions as "the greatest thing I've done", he disbanded the quintet, formed a sextet with an extra bandoneon, cello, bass, electric guitar, and piano, and wrote music for this ensemble that was even more adventurous harmonically and structurally than any of his previous works (Preludio y Fuga; Sex-tet). Had he not suffered an incapacitating stroke on the way to Notre Dame mass in 1990, it is likely that he would have continued to use his popularity as a performer of his own works to experiment in relative safety with even more audacious musical techniques, while possibly responding to the surging popularity of non-Western musics by finding ways to incorporate new styles into his own. In his musical professionalism and open-minded attitude to existing styles he held the mindset of an 18th century composing performer such as Handel or Mozart, who were anxious to assimilate all national "flavors" of their day into their own compositions, and who always wrote with both first-hand performing experience and a sense of direct social relationship with their audiences. This may have resulted in a backlash amongst conservative tango aficionados in Argentina, but in the rest of the West it was the key to his extremely sympathetic reception among classical and jazz musicians, both seeing some of the best aspects of their musical practices reflected in his work.
Piazzolla, after leaving Troilo's orchestra in the 1940s, led numerous ensembles beginning with the 1946 Orchestra, the 1955 "Octeto Buenos Aires", the 1960 "First Quintet", the 1971 "Noneto", the 1978 "Second Quintet" and the 1989 "Sextet". As well as providing original compositions and arrangements, he was the director and Bandoneon player in all of them. He also recorded the album Summit with jazz baritone saxophonist Gerry Mulligan. His numerous compositions include orchestral work such as the "Concierto para Bandoneón, Orquesta, Cuerdas y Percusión", "Doble-Concierto para Bandoneón y Guitarra", "Tres Tangos Sinfónicos" and "Concierto de Nácar para 9 Tanguistas y Orquesta", pieces for the solo classical guitar -- the "Cinco Piezas", as well as song-form compositions that still today are well known by the general public in his country, like "Balada para un loco" (Ballad for a madman) and Adiós Nonino (dedicated to his father) which he recorded many times with different musicians and ensembles. Biographers estimate that Piazzolla wrote around 3,000 pieces and recorded around 500.
