The John Adams 1985 work "Harmonielehre" is featured, with other sounds. From Wikipedia: "John Coolidge Adams (born February 15, 1947) is an American composer, clarinetist, and conductor of classical music and opera, with strong roots in minimalism." And "Harmonielehre is a 1985 orchestral composition by the American composer John Adams. The composition's title, German for "study of harmony," is also the title of several music theory texts, including those written by Arnold Schoenberg (1911), Heinrich Schenker (1906), and Hugo Riemann (1893), with Adams explicitly referring to Schoenberg's."
