Score-John Adams's creative output spans a wide range of media: works for orchestra opera video film and dance as well as electronic and instrumental music. Such pieces as Harmonium Harmonielehre Shaker Loops and The ChairmanDances are among the best known and most frequently performed of contemporary American music. In these works he has taken minimalism into a new and fresh terrain characterized by luminous sonorities and a powerful and dramaticapproach to form.
