This recording is part of the extensive Orgelwerke series released by the East German label ETERNA, which sought to document the organ works of Johann Sebastian Bach. It features Johannes-Ernst Köhler, a prominent German organist who served as the organist of the Weimar City Church, performing on the historic Silbermann organ. The production reflects the high regard for historically significant instruments in East Germany, aiming to capture the authentic acoustic character of the baroque-era Silbermann organs for a classical music audience.

The album features a selection of Bach's organ compositions, including the Trio Sonatas and the Toccata, Adagio, and Fugue in C Major. The design and liner notes of ETERNA releases from this period often emphasized the technical specifications of the instruments and the scholarly rigor of the performances. As a label, ETERNA became internationally recognized among collectors for the meticulous quality of its classical catalog, which preserved the work of East German performers during the mid-20th century.
