The internationally renowned trumpeter Markus Stockhausen will turn the Arithmeum into a special tonal space and invites the public to listen: together with his brother, Simon Stockhausen – with whom he has already realized many musical projects – on synthesizer and saxophone, as well as the Dutch clarinettist Barre Bouman – an expert in New Music, and the French percussionist Patrice Héral – with whom he has been collaborating closely for three years and whose humor and joyous playing enthrall the audience.
