Robert Köbler An Der Silbermannorgel Zu Grosshartmannsdorf (Fantasie G-dur / Allabreve D-dur / Fantasie Und Fuge C-moll / Präludium Und Fuge E-moll / Fuge C-moll / Fuge G-moll / Präludium Und Fuge A-moll)

Released in 1967 on the East German state-owned label ETERNA, this recording captures organist Robert Köbler performing the works of Johann Sebastian Bach. The album is significant for its setting, as it was recorded at the Silbermann organ in Großhartmannsdorf, an instrument crafted by the renowned Baroque organ builder Gottfried Silbermann. The project was part of ETERNA's broader mission to document the historic instruments of the German Democratic Republic alongside the canonical works of the German musical heritage.

The recording highlights the synergy between Bach’s compositions and the specific tonal characteristics of the Silbermann instrument. Köbler, a respected interpreter of the organ repertoire in East Germany, sought to convey the nuanced registration and clarity of sound inherent to the mid-18th-century instrument. At the time of its release, the record was well-regarded by scholars and enthusiasts of organ music for its faithful representation of a preserved historical acoustic environment, serving as both a technical showcase and a preservationist effort.
