It really is a spectacular sight when four organs, two choirs and several wind ensembles play together at the same time. At the “Music for Advent and Christmas” concert in St Michael’s Church, conducted by Günther Jena, a composition for this unusual ensemble formed the highlight and finale. Bertold Hummel had written a fantasia based on the Sicilian Christmas carol “O du fröhliche, o du selige” especially for this concert. All the organs and positive organs in “Michel”, along with their locations, were incorporated into the musical performance. Hummel combines apocalyptic foreboding with the joyful message of Christmas. Particularly impressive were the masses of sound emanating from virtually all four corners of the church (from three galleries and the chancel).
