"Waiting for the Barbarians", an opera from J. M. Coetzee's novel (with the libretto by Christopher Hampton), had its premiere performance in September 2005. Glass defined the work as a "social/political opera", as a critique on the Bush administration's war in Iraq, a "dialogue about political crisis", and an illustration of the "power of art to turn our attention toward the human dimension of history". While the opera's themes are Imperialism, apartheid, and torture, the composer chose an understated approach by using "very simple means, and the orchestration is very clear and very traditional; it's almost classical in sound", as the conductor D. Russell Davies notes.
