Sorry for this shameless self-promotion, but an article I recently wrote for the Journal of Musicological Research has just been published and can be accessed online. It deals with Stockhausen's comments about 9/11, and attempts to look at the character of Lucifer through the lenses of Adorno and Lacan to give some critique and commentary on Stockhausen's remarks about the 9/11 attacks as the art of Lucifer.
I feel that it could be useful to have a discussion-forum on the music of Stockhausen. There are so many people from all over the world, young and old, learned and eager to get into contact with this musical world: musicologists, composers, musicians, music lovers; people who plan concerts - who write books or have to give lectures and so on. So there should be much stuff, many ideas that we can share. And when we have open questions, there may be people who studied just that and could give a hint or a stimulus.
A problem might be the English language, but i feel that is the only possibility that many people who are interested can participate. And we can exercise tolerance to mistakes!
