?This volume is decidely a labor of love.... The work is not merely a catalog of all the piano compositions (solo, four hands, two pianos, piano and orchestra, arrangements, transcriptions, hybrid works, unpublished works) as the title might imply, but a vast descriptive, critical, and sometimes analytical essay. The splendid, many-faceted treatment was almost necessary if the author were to fulfill his aim to throw some light on Busoni's thought processes as a composer and performer and to interest pianists in performing Busoni, ' He thus treats many areas of the composer's work, such as his theory of notation, his compositional growth, etc. Essential for academic music collections.?-Library Journal
