That’s The Conquest of Mexico, an historical music drama composed in 1991 by German composer Wolfgang Rihm (b. 1952). But wait. Wolfgang Rihm construed a few sentences of Artaud’s La ConquÍte du Mexique (1932) mixed up with bits of Aztec chant and bits of poem(s) by Mexico’s Octavio Paz (d. 1998) to make a libretto.
