Maryanne Amacher (1938-2009) was a composer of large-scale fixed-duration sound installations and a highly original thinker in the areas of perception, sound spatialization, creative intelligence, and aural architecture. She is frequently cited as a pioneer of what has come to be called “
sound art,” although her thought and creative practice consistently challenges key assumptions about the capacities and limitations of that genre. Often considered to be a part of a post-
Cagean lineage, her work anticipates some of the most important developments in network culture, media arts, acoustic ecology, and sound studies.
