Charles Peter Wuorinen ( ; June 9, 1938 – March 11, 2020) was an American composer of contemporary classical music based in New York City. He also performed as a pianist and conductor. Wuorinen composed more than 270 works: orchestral music, chamber music, solo instrumental and vocal works, and operas, such as Brokeback Mountain. His work was termed serialist but he came to disparage that idea as meaningless. Time's Encomium, his only purely electronic piece, received the Pulitzer Prize. Wuorinen taught at several institutions, including Columbia University, Rutgers University and the Manhattan School of Music. Source: Wikipedia (en)
