The Annaberg Walcker-Eule organ is a real jewel and the digital translation a great sampleset.
I already uploaded parts of Reger's opus 135a, which almost everybody will have played sometime in bunches of three and four.
As I did already half of them and they are fairly often listened to and favourably commented on, I'll upload the complete bunch of thirty.
The small preludes, written late in life a few years before his death, belong to Reger's finest compositions.
Most of them are no more than exquisitely chosen chorale settings in Reger's inimitable style.
