The Annaberg Walcker-Eule organ is a real jewel and the digital translation a great sampleset. It has already been presented with many bigger pieces by Reger and other composers.
I intend to upload parts of Reger's opus 135a, which almost everybody will have played sometime, in bunches of two and three.
Moreover the small preludes, written late in life a few years before his death, belong to Reger's finest compositions.
00:00: #02 Allein Gott in der Hoh sei Ehr
02:03: #21 O Haupt voll Blut und Wunden
05:32: #25 Wachet auf rust uns die Stimme
Because of the realistic dynamics of this excellent sampleset # 21 was boosted by 3 dB between the louder #02 and # 25.
