Marpurg's prelude to "Wenn Christus seine Kriche schützt" has the choral melody in the pedals. It has a march-like rythm, a playing indication "Heroic" and together with the melody in the pedals that begs for a plenum registration. Perhaps that registration choice is a bit too obvious, a more original approach is the one EdoL took: https://www.contrebombarde.com/concerthall/music/42072
Somehow I did not mount the camera properly (again), so in the second half of the video you don't see my hands any more, only my head and shoulders. Since I recorded this video I invested in some new gear, so I hope it won't happen in newer videos.
