After five volumes devoted to the early years of J. S. Bach, up to the Weimar period, Benjamin Alard takes an utterly fascinating approach to the first book of The Well-Tempered Clavier. First he offers the listener an astonishing mental preparation on the clavichord, derived mainly from the Clavier-B�chlein for Wilhelm Friedemann. Then he arranges the preludes and fugues in a new order. To play his program he has chosen two instruments from the glorious Hass family of instrument builder, s who possess a festival of colors and registrations each more breathtaking than the last.
