Bach: Organ Works, Vol. 3 & 4 (At the Organ of Saint James’ Church in Hamburg)

These volumes from Bach’s complete organ cycle by Ton Koopman include the trio sonatas and various prelude and fugues, amongst them the Dorian and the famous D Minor. They are performed on a splendid instrument from Hamburg by Arp Schnitger, the most influential organ builder of 17th-century Northern Germany.
