What Made It So Hard to Record This Piece?

I worked on this piece by Dieterich Buxtehude (Der Tag, der ist so freudenreich, BuxWV 182) for 3 days and almost gave up recording it. But the last take turned out fine. I asked Vidas to listen to it and we both saw that it would sound quite convincing. This is a beautiful ornamented chorale prelude and now that I'm listening to it, I think I'm quite liking it which is rare for my own recordings. Let me know what you think.
