The horn concertos by Wolfgang Amadeus Mozart have always been part of the standard repertoire of every horn player. Tyrolean hornist Hansjörg Angerer presents the four horn concertos with the Ensemble Salzburger Hofmusik under the direction of Wolfgang Brunner, performed on an original instrument crafted by an unknown Bohemian master from around 1800. The complex playing techniques on this instrument, along with distinctive sound, differ significantly from those of a modern valve instrument, offering a profound exploration of the great variety of colours prevalent in the music of this era.
