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.
