Harpsichordist Gilbert Rowland has completed a substantial project with his recording Johann Mattheson 12 Suites for Harpsichord (Athene ath 23301.1 divineartrecords.com). The three-disc set is a valuable document shedding some light on the music of a hitherto obscure composer. Mattheson was a contemporary of Handel and came to know him well as a friend and colleague. He is said to have written numerous operas, oratorios, sacred works and music for organ. Most of these manuscripts were kept in Hamburg, where Mattheson lived and worked for much of his life. Allied bombing of the city during WWII destroyed most of the Mattheson documents, leaving little for modern scholars to study. Fortunately, the 12 Suites for Harpsichord, dating from 1714, have survived. They are well-conceived mature works written in the French dance suite style. Rowland plays a 2005 copy of a French instrument from 1750 by Goermans.
