Most great composers have left some works that are rarely heard. They may not be part of a better-known set, or may contain odd features which are not typical of a master’s more familiar style. Colin Booth’s CD features music of this kind. His three previous Bach recordings (J. S. Bach – by Arrangement; the Goldberg Variations, and the Well-Tempered Clavier), have all attracted extravagant critical praise. Here we have a collection of unfamiliar keyboard gems which make immediately compelling listening. Also, as a theme, the program investigates how Bach carried home from church his organ-playing style, allowing it to make its mark upon his music for domestic instruments, for instance his use of very long held notes in supposed harpsichord works, something that his contemporaries Handel and Scarlatti did not do.
