VOLUME 3: I. Ending to Dr. Faust II. Definitive version of the Fantasia Contrappuntistica for two pianos III. Concerto for Orchestra: Completion and orchestration of the Fantasia Contrappuntistica. Larry Sitsky, professor emeritus at The Australian National University, is an internationally known composer, pianist, scholar, and teacher. His books are fundamental reference works on subjects such as Australian piano music, the 20th-century avant-garde, the piano music of Anton Rubinstein, the early 20th-century Russian avant-garde, and the classical reproducing piano roll. The Compleat Busoni is the result of Sitsky's lifelong focus on the composer Ferruccio Busoni. Over three volumes, Sitsky surveys Busoni's vast output, provides an ending to the unfinished opera Dr. Faust, and presents definitive realisations of the Fantasia Contrappuntistica in two-piano and orchestral versions. New insights into Busoni's style and aesthetics are an integral aspect of this work.
