Theater aan het Spui will form the backdrop for Stockhausen’s Kathinka’s Gesang (Als Luzifers Requiem Vom Samstag Aus Licht) for solo flute and six percussionists. Artist-in-residence Christian Karlsen will conduct the Royal Conservatory Orchestra with a performance of the opera Michael’s Reise um die Erde (vom Donnerstag aus Licht) for trumpet and orchestra. Stockhausen opened a new world of sound when he wrote this visionary music. Marco Blaauw, a Dutch trumpeter and eminent Stockhausen-interpreter, will play the role of the archangel Michael.
