For decades, Matthias Eisenberg has enchanted audiences with his improvisations on self-chosen or given themes, causing them to cheer. In this year's Christmas Organ Music on 25.12., he will improvise on well-known Christmas carols, but first present himself as a profound Bach interpreter again and perform some gems from Bach's rich oeuvre with the “Orgelbüchlein-Choräle”, one of the six trio sonatas and Prelude and Fugue in G major as an “overture”.
