This is acclaimed organist, composer, and recording artist Hans-Andre Stamm performing at the historic, world famous Trost organ of the Evangelical Lutheran City Church (Stadtkirche) of Waltershausen, Germany.  This Trost organ is a period instrument that Bach himself knew and likely played which has been kept in original and fully playable condition.  It's the largest mechanical action organ in Thuringia, the region of east-central Germany where Bach was born and lived his entire life.

Prior to its appearance nothing as powerful as this d minor BWV (Bach-Werke-Verzeichnis) listing 565 had ever appeared in the organ literature before [See blog, Bach d minor, Parts I-V].  This is a work heavily influenced by the north German multi-sectional "stylus phantasticus" form and was written by a musician whose independent mastery is evident.  The likelihood that any other German organist at the time, save for J.S. Bach, could have written a work of such unprecedented force, energy, and strength is remote.  It is thus believed to be a youthful work which, in its original form, was produced some time during young Sebastian Bach's Arnstadt years (1703-1707).  

This is as close to a gold-standard recording of this work as it comes.  The listener will note the excellent camera work in this video, that no registration changes were made in this recording from start to finish, that the sound was varied only by changing manuals, that the German chorus reed stops of Bach's time were not dominating, that the 32-foot reed (Posaune) is tame, that it is kept drawn the entire time save for the first half of the central fugal section, that the tempos were very brisk but never too fast, and that a mixture of all 5 types of touch (including thumbs on the black keys at times) were employed here in a fine, stylistic performance of this famous work [See blog, Bach d minor, Part I].

We offer our compliments and sincerest thanks to Mr. Stamm for making this outstanding recording and posting it on YouTube for public viewing.
