Holly Herndon and Mat Dryhurst’s Starmirror (2025), a new immersive sound installation created with sub architects, transforms Berlin’s KW Institute for Contemporary Art into a training ground for a public choral dataset. During recording sessions, choirs sing from an AI-generated songbook based on a morality play by medieval mystic Hildegard von Bingen. “We see analogies between her celestial hierarchy and the stack of influential protocols that determine our culture,” the duo notes.
