At the centre of the perception of César Franck as an organ composer are the twelve large-scale works, which are counted among the most radiant contributions to the organ literature. However, it should not be forgotten that with the collection "L'Organiste" he wrote 63 shorter, but compositionally very elaborate pieces, which due to their vignette-like, compact facture do not reach the complexity of his "large" organ works, but are nevertheless very remarkable: Each one of the pieces has a signature all its own, and is in no way inferior to Franck's extensive organ works in terms of harmonic complexity and focus of expression. It is thanks to our interpreter, i.e. Carsten Wiebusch's knowledgeable and tasteful arrangement of this collection originally composed by Franck for harmonium, that these miniatures can fully unfold their coloristic potential on the organ. And last but not least, there was the fascinating task of selecting the appropriate instruments for a Franck complete recording. What today appears so clearly arranged on 4 CDs with three organs is the result of a thought process lasting several years, during which many instruments were considered, tested and discarded again in order to impressively reproduce the versatility of Franck's music.
