Sigfrid Karg-Elert (November 21, 1877 – April 9, 1933)
Op65 No51 Schmücke dich, o liebe Seele. Karg-Elert Chorale Improvisations op 65. 66 organ pieces composed between 1906 and 1908. They were first published in 1909 and dedicated to Alexandre Guilmant. Op 65 includes the well known Nun danket alle Gott.
I've been uploading the less complex pieces of Opus 65 on the Oberlinger organ in Bonn but was sure the Metzler Poblet sample could handle Karg-Elert and it does seem to adapt to this style of music quite well.
