Bach: 48 Preludes and Fugues: The Well Tempered Clavier.

Some 250 years after the death of Johann Sebastian Bach, four noted classical pianists tackle the composer's "The Well-Tempered Clavier," a collection of keyboard pieces often referred to as the "Old Testament of piano literature." The program features soloists Nikolai Demidenko, Andrei Gavrilov, Joanna MacGregor and Angela Hewitt performing in Venice, Italy; Barcelona, Spain; Oxford, England; and Bach's birthplace of Eisenach, Germany.
