John Coolidge Adams is a Pulitzer Prize-winning American composer with strong roots in minimalism. His best-known works include Short Ride in a Fast Machine, On the Transmigration of Souls, a choral piece commemorating the victims of the September 11, 2001 attacks (for which he won the Pulitzer Prize for Music in 2003), and Shaker Loops, a minimalist four-movement work for strings. His well-known operas include Nixon in China, which recounts Richard Nixon's 1972 visit to China, and Doctor Atomic, which covers Robert Oppenheimer, the Manhattan Project, and the building of the first atomic bomb.
While Adams employs minimalist techniques, such as repeating patterns, he is not a strict follower of the movement. Adams was born a generation after Steve Reich and Philip Glass, and his writing is more developmental and directionalized, containing climaxes and other elements of Romanticism.
