In 1758 the London publisher John Walsh, sensing a marketing opportunity, issued a collection of harpsichord sonatas under the name of Johann Adolf Hasse. The volume includes genuine compositions by Hasse alongside some works that are in all likelihood not by him. Walsh's editorial decisions reveal a discerning musical judgment, and the pieces gathered in the collection are of consistently high quality. The present recording offers the complete set, performed on an original 1768 harpsichord by the Amsterdam builder Carl Fredrik Laescke.
