Nun lob, mein Seel, den Herren

Johann Gottfried Walther (1684-1748) was a German music theorist, organist, composer, and lexicographer of the Baroque era. Not only was his life almost exactly contemporaneous to that of Johann Sebastian Bach, he was also his cousin. He has written mostly organ works; many chorale preludes, variations, concerti, toccatas, preludes, fugues etc.

This tricky chorale prelude on the hymn 'Nun lob, mein Seel, den Herren' has a canonic structure with both the cantus firmus in the soprano and the bass (pedal).
Listening back to this recording (which I recorded a few months back) I think the amount of reverb is quite a lot, maybe too much. But on the other hand, it gives you a good impression of how this organ sounds in the back of the church room, where people are seated too ;)
