Ma ünnepli születésnapját a portugálok remek zongoristája, Maria João Pires. Ő volt az, aki teljesen más Mozart-zongoraversennyel érkezett egy nyilvános zenekari próbára. A karmester, Riccardo Chailly gyors rábeszélésére aztán a másik koncertet is eljátszotta.
Piazzolla, Astor (1921-1992). Argentine composer, bandleader and bandoneón player. A child prodigy on the bandoneón, Piazzolla and his family emigrated to New York in 1924; in his teens he became acquainted with Gardel, for whom he worked as a tour guide, translator and occasional performer. Piazzolla returned to Buenos Aires in 1937 where he gave concerts and made tango arrangements for Aníbal Troilo, a leading bandleader; he also studied classical music with Ginastera. In 1944 Piazzolla left Troilo’s band to form the Orquesta del 46 as a vehicle for his own compositions. A symphony composed in 1954 for the Buenos Aires PO won him a scholarship to study in Paris with Boulanger, who encouraged him in the composition of tangos; the following year he resettled in Argentina and formed the Octeto Buenos Aires and, later, the Quinteto Nuevo Tango, which performed at his own club, Jamaica. Piazzolla left Argentina in 1974, settling in Paris, where he composed a concerto for bandoneón and a cello sonata for Rostropovich, among other works. (According to Cliff Eisen in GroveOnline)
