This album of French piano rarities features seldom-heard and recently discovered works by composers who had an influence on Pierre Boulez, as well as the premiere recording of Boulez’s Prélude, Toccata et Scherzo. This large-scale early work looks back on virtuosic Romantic music, while at the same time exploring the new compositional styles that Boulez would subsequently embrace. Among the rarities is a posthumously discovered piano study by Debussy, a reconstructed birdsong work by Messiaen, and a tiny masterpiece by Ravel found in a notebook.
