Ástor Pantaleón Piazzolla (March 11, 1921 – July 4, 1992) was an Argentine tango composer and bandoneón player. His oeuvre revolutionized the traditional tango into a new style termed nuevo tango, incorporating elements from jazz and classical music. A virtuoso bandoneónist, he regularly performed his own compositions with a variety of ensembles.
Piazzolla was born in Mar del Plata, Argentina, in 1921, the only child of Italian immigrant parents, Vicente "Nonino" Piazzolla and Asunta Manetti. His grandfather, a sailor and fisherman named Pantaleón Piazzolla, had immigrated to Mar del Plata from Trani, a seaport in the southeastern Italian region of Apulia, at the end of the 19th century.
