What might one expect from an album entitled ‘Clair-Obscur’? Art songs from Debussy, Fauré, or Duparc perhaps with a particularly nocturnal ambiance? The program from soprano Sandrine Piau in her latest Alpha release focuses not on French chanson, but on German, early-to-late twentieth-century Viennese orchestral songs. Not repertoire immediately associated with Piau, who recorded extensively earlier music in recent times. The booklet highlights that she is returning to music she adored in her student years.
