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. Musical career After leaving Troilo's orchestra in the 1940s, Piazzolla led numerous ensembles beginning with the 1946 Orchestra, the 1955 Octeto Buenos Aires, the 1960 "First Quintet", the 1971 Conjunto 9 ("Noneto"), the 1978 "Second Quintet" and the 1989 New Tango 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 (Reunión Cumbre) 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 (1980), as well as song-form compositions that still today are well known by the general public in his country, including "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. In 1984, he appeared with his Quinteto Tango Nuevo in West-Berlin, Germany and for television in Utrecht, Netherlands. In the summer of 1985 he performed at the Almeida Theatre in London for a week-long engagement. On September 6, 1987, his quintet gave a concert in New York's Central Park, which was recorded and, in 1994, released in compact disc format as The Central Park Concert. Legacy Astor Piazzolla International Airport in Mar del Plata is named after him. Buenos Aires music conservatory "Conservatorio Superior de Música de la Ciudad de Buenos Aires" carries his name Google celebrated his 100th birthday on 11 March 2021 with a Google Doodle.
