Volume 4 of Benjamin Alard's complete recording of Bach's keyboard works continues to explore the Weimar period. After A la francaise, we turn to Italy, where the Vivaldian concerto reigned in Venice. The young Bach created here a wonderful space of freedom between the transcriber and the improviser. Benjamin Alard performs on three exceptional instruments, including a magnificent 1702 harpsichord by Mattia de Gand, preserved in Treviso and recently restored.
