NEW YORK (AFP)Avant-garde composer Elliott Carter, who won the Pulitzer Prize twice in a career spanning nearly eight decades, has died in New York at the age of 103, a music publisher said Tuesday. Carter had composed 158 works, from early pieces like Symphony No. 1 (1942) and Holiday Overture (1944) to this year’s Dialogues II, which premiered last month in Italy, and Instances, which is set to debut in February.
