There are individual rolls of music which contain recordings of great music-historical value. Triggered by the discovery of two special Hupfeld scrolls with Kenneth Hamilton, After the Golden Age - Romantic Pianism and Modern Performance has written a fantastic book about the performance style of the great pianists and composers from the Romantic period to the modern age. He has studied countless sources and describes in detail the different views and forms of performance of the pianists. With numerous quotations and anecdotes, the book, written in English, is very lively to read and provides a great deal of insight for a better understanding of the recordings, some of which have been preserved on scrolls.
