Église Saint-Eustache .
The common theme linking the events of Agora 2011 is that of Stockhausen, master of computational frenzy and visionary intuition.
The man who forged and traveled each path until exhaustion—electronic music in the concert hall space or in opera, writing the absolute order or the freedom of intuitive music—conceived his oeuvre as prospective and archetypical. A substantial journey that bends from the original to the "primeval", from the force of youthful beginnings toward the praising of origins in later works. Crossing through Agora and several Parisian locations, the instants of Klang, the ultimate unfinished cycle by Stockhausen, calls for a final time the unity of the totality shared on the world stage.
