Undoubtedly one of the great preludes and fugues of the master which gives this instrument a chance to stretch it's more baroque legs!
I have used the divisions of the organ that sit forward of the arch, namely Hauptwerk / Pedal and Ruckpositiv and I think they give a fine, dignified account of themselves.
I do allow myself the pleasure of the 32' Posaune for the final entry in the fugue, but I think that it works appropriately in this plenum.
This is a straight through take so please forgive the occasional infelicity!
