Music Concrete

(Quote: Stockhausen on the 9/11 attack)
'What has happened is - now you all have to turn your brains around - the greatest work of art there has ever been. That minds could achieve something in one act, which we in music cannot even dream of, that people rehearse like crazy for ten years, totally fanatically for one concert, and then die. This is the greatest possible work of art in the entire cosmos. Imagine what happened there. There are people who are so concentrated on one performance, and then 5000 people are chased into the Afterlife, in one moment. This I could not do. Compared to this, we are nothing as composers... Imagine this, that I could create a work of art now and you all were not only surprised, but you would fall down immediately, you would be dead and you would be reborn, because it is simply too insane. Some artists also try to cross the boundaries of what could ever be possible or imagined, to wake us up, to open another world for us.'
Karlheinz Stockhausen, Hamburg, September 2001.
