Janus (mobile 2011), for flute and guitar, approaches the theme of indeterminacy by presenting two very distinct musical pathways in the form of two relatively independent and virtuosic “solos.”  Here, the task of each performer is to hold the course (i.e. the independent character of their own part) in the face of interaction cues that constantly force them back into a chamber music situation (i.e. listening and reacting to their partner).
