Sense, joy of discovery and sometimes happy coincidences repeatedly lead to first editions of works that would otherwise remain hidden from the public. In the case of this private find of a hitherto completely unknown pastoral mass by the Silesian composer lgnaz Reimann in a small music collection from the immediate vicinity of his place of work, Albendorf. The work, so richly endowed with the "pastoral charms" so typical of Reimann, can be performed in various instrumentations: with a full orchestra, only with strings and organ or even only with organ, for which the editor has created his own, easily playable organ version. For many choirs, Reimann has been part of Christmas for decades like "Silent Night" and "Transeamus". This "new" pastoral mass should not only delight these choirs, but also increase the circle of Reimann enthusiasts. With credo.
