Composer John Adams. Although he comes out of the classical tradition, Adams is not afraid to use drum machines, synthesizers and silent-movie chord progressions in his music. His latest work, "The Wound Dresser", is a setting of a poem by Walt Whitman about the experience of tending wounded soldiers during the Civil War. For Adams, the work has connections to both the AIDS crisis and his father's recent battle with Alzheimer's disease. Adams also talks about his best-known work, the opera "Nixon in China".
