A friend of mine, Bastian Fuchs, played this wonderful sonata as a "warm-up" piece on the "Grand Opening" (German: Orgelweihe) of my GrandOrgue setup at home on the 18th Oct 2014. I was very glad that he joined and rocked the show...! :)
If you're interested in hearing more of his stuff, you can find him on YouTube at https://www.youtube.com/user/derCarilloneur
P.S.: My favourite part is from 7:36
. No other recital of it could ever reproduce the goose bumps I always get when I listen to this heroic passage with that more-than-fitting registration on that nice Walcker organ... Thanks again, Bastian...!
Btw, I noticed that the sample set is not directly linked here on CCH, so here is the URL: http://www.walckerwildervank.nl/
-- Eventually, one of the CCH admins would like to add it to the database.
