The sixth volume of Busoni’s piano music features two major projects from the earlier part of his career. The Liszt transcription powerfully recreates the composer’s grandest work for organ in terms of the piano, while the Piano Sonata in F minor is an exhilarating example of late-Romantic virtuosity that remained unknown until recent decades. In total contrast, the brief Prélude et étude en arpèges finds Busoni’s late musical language at its most concentrated and refractory.
