“Athroa” is a composition that combines an improvised electroacoustic performance with an interactive light installation. In this composition, space, rather than time, is the basis of formal organization, and the experience of the music will be embodied in the process of navigating through space and observing objects from different vantage points. The music is in counterpoint with a light installation which interacts with the sounds and musical textures in non-obvious (non-rhythmical) ways.
