The Prelude and Fugue in E Minor, BWV 533, has been called "The Cathedral" and also "The Nightwatchman's" (because of the Fugue subject).
The influences of Buxtehude are obvious, but we see Bach's metmaorphoses of them. Schmeider places this work in the Weimar period and dates it around 1707. Commentators are generally agreed that the somewhat somber feeling of this work foreshadows the more clearly and nobly realized solemnity of Bach's later and grander organ works.
I actually did this recording, and a number of others, almost a month ago to show off the new and beautiful Kahn organ of the St. Michael's Church in Hungary. It is a beautiful instrument, and VERY modestly priced!
Unfortunately, my hearing went into a very bad stage, and I just sort of "disappeared" from the CH.
I had done this piece to use as a Postlude after "O come, O come, Emmanuel," which matched the mood and tone very well. Since we are almost out of Advent, I will only post one or two of these recordings.
