The Epic is a twelve-tone choral work for 12 singers and 18-channel panaural microphone array. Each member of the choir represents one semitone in a chromatic scale; they stand in a circle, each member a perfect fifth apart from those next to them. All the voices sound at once in a single simultaneous twelve-tone chord, an intense wall of sound which nonetheless continually mutates as the choir and audience move through the room, creating progression and even melody within the frozen noise.
