Book excerpt: "We haven't even made it to breakfast!" Composer Maryanne Amacher (1938-2009) often used this phrase to shorthand her critical and partial approach to knowledge production across the vast artistic, technical and scientific discourses with which she worked. The same could be said about her own musical thought, which encompassed original presentational formats in existing and speculative media and approaches to sound and listening that conjoined real and imagined social worlds. In these conjunctions, this book discerns meeting points between frameworks for life that emerged from Amacher's multidisciplinary study of sound and listening: within acoustical spectra, inside human bodies and ears, across cities and edgleands, hypothetical creatures and virtual, fictive or distanciated environments. These figurations guide interpretative study of six signal projects: Adjacencies (1965/1966); City-Links (1967-1988); Additional Tones (1976 / 1988), Music for Sound-Joined Rooms (1980), Mini Sound Series (1985) and Intelligent Life (1980s) and countless sketches, notes and unrealized projects. The book explores Amacher's working methods with an interpretive style that emphasizes technical study, conceptual juxtaposition, intertextual play and narrative transport. This book also takes up Amacher's work as a guiding thread across shifting social discourses on life in the late 20th century U.S. Her projects convoked figurations of life and technoscience that could be partially and ironically accessed or conceptualized via complex auditory thresholds. This nascent feminist epistemology rooted in feminist science and technology studies centers biopolitical questions about difference and power in artistic and critical work that counts Amacher among its precedents"--
