Anterior/Interior was written for flutist Carla Rees. Anterior refers to our initial experience with the sound of the flute - the external shape that we hear, before entering into the sound. The interior can be found in the smaller, quantum level relationships contained within this shape. Real-time digital processing allows for intense magnification and dissection of the flute's sound, revealing beautiful inner rhythms and harmonies, always present but not easily apprehended.
