In this brief article, through descriptions of three of her works - The Logic of Waste (1989), Voices Lost and Calling (1990) and Highways to Virtuality (1991) - the author outlines some of the theoretical concepts and strategies that underline her work, and the way they relate to both her compositional practice and choice of aural material. Through this description, central concerns of her work - such as the impact of technology, the Western world-view and the status of sound in Western culture, ecology and militarism - are exemplified, and the importance of audio art as an appropriate medium for addressing these issues is highlighted.
