For decades, Peter Ablinger’s work has been forcing open fault lines in the topography of the audible. His vast output of scores, electronic pieces, installations, and conceptual works consistently finds ways—funny, pointed, disturbing—to put the ear’s organization of reality in doubt. Is that a voice, and what is a voice? When is something newly or no longer music? Noise? Information? In Ablinger’s cunning scramble of sonic categories, listening loses its lay of the land. Concepts come unmoored from sounds, and the land changes shape.
