The Well-Tempered Clavier -- Andras Schiff (1984)

http://www.bachwelltemperedclavier.org/

"The Well-tempered Clavier belongs to the major musical achievements of the Baroque age in Europe, and it is until today an intellectual challenge for musicians and listeners alike, as well as a deep and seemingly inexhaustible source of inspiration. JS Bach, like no other composer in musical history, managed to combine rather abstract and formal concepts, such as counterpoint, fugues and canons, with an incredible sense of beauty. The variety and depth of the pieces, the mastership with which JS Bach uses popular musical forms and types of the time (such as italian concerto, trio sonata, ricercare, and many others) and transforms them into something unique and entirely sophisticated, provides a vast playing field for musicians to both learn from and express sublime musical thoughts."
