Edge was composed for the Righteous Girls and is featured on their critically acclaimed release, gathering blue. A knife-edged glitchy rhythmic unison between piano and flute opens the piece, staccato stabs blurred by brief legato bursts. Delicate moments of stasis barely stave off the alternating eruptions from flute and piano. Nevertheless, these calm oases eventually emerge triumphant, Edge ending with soft piano harmonics and whistle tones. Approximately 7 minutes in duration.
