As a composer, Anthony Davis is best known for his operas. X, The Life and Times of Malcolm X, which played to sold-out houses at its premiere at the New York City Opera in 1986, was the first of a new American genre: opera on a contemporary political subject. The recording of X was released on the Gramavision label in August 1992 and received a Grammy Nomination for "Best Contemporary Classical Composition" in February 1993. Davis's second opera, Under the Double Moon, a science fiction opera with an original libretto by Deborah Atherton, premiered at the Opera Theatre of St. Louis in June 1989. His third opera, Tania, with a libretto by Michael-John LaChiusa and based on the abduction of Patricia Hearst, premiered at the American Music Theater Festival in June 1992. A recording of Tania was released in 2001 on Koch, and in November 2003, Musikwerkstaat Wien presented its European premiere. A fourth opera, Amistad, about a shipboard uprising by slaves and their subsequent trial, premiered at the Lyric Opera of Chicago in November 1997. Set to a libretto by poet Thulani Davis, the librettist of X, Amistad was staged by George C. Wolfe.
