Kurt Estermann is a juror for the Slatkonia Prize of the Archdiocese of Vienna and the music promotion prize of the Federal Chancellery, and as a church musician he is closely associated with the Wilten Abbey in Innsbruck.
In 2000 he was appointed to the chair for church composition at the Mozarteum University in Salzburg. His compositional work includes mainly organ music, works for voice and organ, choral works, orchestral and ensemble music. They appear at Doblinger Vienna .
The fascination for the organ extends not only to the compositional search for new sound possibilities, but also to researching and raising awareness of the organ as a historical instrument in this context. In this sense, Kurt Estermann is the editor of two series of books that are published in Helbling-Verlag Innsbruck appear: "Tiroler Orgelschatz" and "Studia Wilthinensia Artis Organi". Unique sound monuments should be better understood in their tradition, with their artistic and innovative craftsmanship, with their history and their protagonists. In this respect, sound research - as a guide to the future - also deals with the past.
