born March 11, 1921, Mar del Plata, Arg.
died July 5, 1992, Buenos Aires
Argentine composer.
He lived in the Bronx, N.Y., until he was 15; he then returned to Argentina to play bandoneon (a type of accordion) in a tango band led by Anibal Troilo (1917–75). From 1944 he led his own groups. His interest in classical music led to study with Nadia Boulanger (1954–55) and the development of his own compositional style, infusing elements of jazz and modern music into tango. Not always initially popular with tango fans, his music is now recognized as having revived the genre and greatly expanded its artistic potential.
