Werner Jacob (1938-2006), was a German organist and composer, who has never made into the general public. Even Wikipedia has an article about him only in German, French and Polish. He studied music at the Musikhochschule in Freiburg im Breisgau, then in Darmstadt with Bruno Maderna and Ligeti. The year 1963 saw him appointed organist of the Dreieinigkeitskirche Nuremberg.
He has recorded the "complete works for organ by Bach" for EMI label fron 1975 to 1985 that is now collected in a box that I received as a gift.
I like as "reference edition" another that I have, that of Helmut Walcha, which definitely prefer, but only for reasons of affection: it was the first important LP I bought. Then I bought a Gesamtewerke a of an unknown organist (while walking to the train station of Padua, Italy where I was studying; and then I found Walcha digitized in a thrift store.
Jacobs is - at any rate - considered by experts critics a good interpreter, very fast in execution times, and often able to read in a personal way the joy of the religious message in the Bach chorales.
It seems to me that on the compositions, such as "passacaglia", when compared with MC Alain s' one, this recording is not awesome, but when dealing with these reissues we often find ourselves having to do with analogue recordings remastered that - it seems impossible - to give their best on high end players.
I would have purchased this as Gesamteafgabe? NO, it is worth of it? As a "second opinion" of Bach's organ works yes.
