There are individual music rolls that contain recordings of great value to music history. Prompted by the discovery of two special Hupfeld music rolls with recordings by Liszt’s pupil Arthur Friedheim, this book, Liszt Piano Sonata Monographs by Gerard Carter and Martin Adler, was written. Liszt himself is said to have singled out his pupil Arthur Friedheim’s performance of his Sonata in B minor as the best. The book discusses these recordings and the piece in detail and allows a better understanding of this Liszt work.
