AEOLUS's Karg-Elert edition is enriched by a further volume: for Volume 9 we have been able to record the monumental E.F. Walcker organ (1927) from the Hans-Sachs-Haus in Gelsenkirchen, once again an ideal instrument for Karg-Elert's spectacular late cycles. When it was built, the instrument with its 89 stops on four manuals was considered a prime example of modern organ building at the time. It survived the Second World War unscathed.

At the end of the 1990s, the Hans-Sachs-Haus had to be renovated and the organ had to disappear. In 2018, it was completely restored and installed in the neo-Gothic St Anthony's Church in Papenburg. This new album with Elke Volker is the first recording (stereo and surround sound) of the instrument in its new location. In the church acoustics, its fascinating sound comes across even more splendidly than in the dry acoustics of the former concert hall.
