The music in this album spans a forty-year period from 1948 to 1988 and reflects Dutilleux's stylistic development as a composer. He considered the Sonata to be the first main work in his catalogue and it represents a turning away from tradition and embraces the transformative musical explorations of the day. The Three Préludes are pieces of concentrated atmospheres, 'a kind of study of timbres', in the composer's words, and each are dedicated to a renowned pianist: No. 1 to Arthur Rubinstein, No. 2 to Claude Helffer, and No. 3 to Eugene Istomin. Dutilleux's lively music for the ballet Le Loup ('The Wolf') is heard here in a première recording of the original piano solo version.
