Each is immediately clear that Jarrett just does not have the necessary technology to fulfill the mandate. Just because Jarrett perhaps can play jazz very well, he is far from being a Friedrich Gulda. Duo - Bach: The Well-Tempered Clavier, Book I & Duo - Bach: The Well-Tempered Clavier, Book II, however, are beautifully interpreted by the legendary Friedrich Gulda, technically knotless played, very inexpensive one at that so highly recommended and highly :-)
