Die Kunst der Fuge
Walcha recorded Bach's complete works twice, once in mono (1947–52), and again in stereo from 1956 to 1971. The former (mono) cycle has been digitally re-mastered and re-issued as a 10-CD boxed set. This latter stereo cycle (released 10/09/2001), has been remastered, and repackaged in a 12-CD box. This edition also contains the recording of his own conclusion of the last fugue of "The Art of Fugue" - previously unreleased.
