Bernhard Lang's Differenz/Wiederholung 2 (Difference/Repetition 2) features a trio of an opera singer, a Kurdish Makam singer and a rapper accompanied by an electro-acoustic chamber orchestra of 14 musicians.
Lang is one of the most revered composers of the contemporary European avant-garde, and in his powerful use of repetition, he juxtaposes the aesthetics of turntablism with the idiom of classical works.
Lang introduces the work before Argento's performance.
