The bulk of this disk consists of the first half of the 18 Leipzig Manuscript chorale preludes, which alone makes it worth the price. The G Major and C Minor Preludes and Fugues are excellent icing on the cake. The Silbermann organ (South German style) sounds wonderful with enough brightness to balance the richness of its sound. The 32' Gross Untersatz (literally translated Big Bottom sound) adds the gravity that Bach himself is quoted as appreciating.
The highlights of this disk for me were Komm Heiliger Geist, great playing, a rich plenum (organ talk for full sound) and that 32' Gross Untersatz. Schmucke Dich, what an incredible registration, the cantus firmus (hymn tune) floats ethereally above it all with just the right amount of tremulant. Nun Danket, a great registration and the cantus firmus firmly on top, truly something to be thankful for.
The playing is sensitive and very capable. Though none of these pieces has obvious call for virtuosic technique, Mr. Weinberger's obvious command of the instrument is wonderfully in evidence. This set is the perfect complement to Kevin Boyer's set (on a North German style Marcussen).
