A virtuosic new sonata for flute and piano. The composer writes: "There is struggle at the heart of this sonata and in the way its story develops. The first movement, a fierce battle between flute and piano, depicts some kind of trauma, the echoes of which reverberate through the rest of the work. Almost every theme is in some way a transformation of another, none more so than the chorale, first heard as a mysterious, increasingly menacing chant in the piano, then reappearing in a different guise in each movement. Once the old ghosts are finally banished, the chorale returns for a final time, transformed into a hymn of hope and redemption."
