I am not so sure that it is not important to know something of the background of the music, and I myself do not think that it is correct that Metzmacher knows absolutely nothing about LICHT - though Adorján cites me in that respect. True, Metzmacher asked me, as if he didn't know, but I had the impression that there was some coquetry in it ...And I agree that the result of his conducting was very very good. I have no idea of performing or conducting but I would guess that also for an interpreter it is a good idea to delve into the spiritual background of a piece. Is it possible for a composer to communicate everything in the signs of the score?
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!
