This is music for contemplating number and time and not realize you are doing that. These pieces from Anna Magdalena Bach's notebook are a significant part of the history of western culture, and the music is brilliant, lucid, and passionate. Just as, I suppose, Bach's wife was. Played on harpsichord and clavichord, the work-- not all by Bach-- seems rigourously, mysteriously modern, and the anonymous "Musette in A Major" one could even say had in it the roots of ragtime piano. Last but not least, it's quite possible that Lorraine Hunt Lieberson can never be less than sublime.
