Must be taken as they are
In answer to "eery but wonderful," it is doubly odd that Prelude No. 14 is missing, as the Duo-Art roll that contains it also has No. 15; and the Triphonola roll has Nos. 11, 12, 14, 17, 18 and 21. As the liner notes for this CD is not available here, it's not known what rolls were used; but Busoni recorded all 24 Preludes of Op. 28 for Duo-Art. Whether these performances are representative of Busoni's art, the Wikipedia article has this to say: "His student Egon Petri was horrified by the piano roll recordings when they first appeared on LP and said that it was a travesty of Busoni's playing. Similarly, Petri's student Gunnar Johansen, who had heard Busoni play on several occasions, remarked, "Of Busoni's piano rolls and recordings, only Feux follets [Will-O-The-Wisp] (Liszt's 5th Transcendental Etude) is really something unique. The rest is curiously unconvincing.""
