Non-timeline music makes no attempts to keep the attention of the listener. It exists as if apart from the attention of the listener. The listener is free to come and go. When the listener attends to the music, there is only the 'sound'. The sound is everything. When the listener is away, the music exists anyway. This is certainly a new idea.
Non-timeline music has not taken over the world. It is still extremely radical. In the last few years the major awards in concert music have gone to composers who, I suspect, have not even imagined that there can be another kind of time. These are not former revolutionaries, who have decided to turn back. They are most like figure skaters who have developed ever more refined figures, but who seem to have missed out on the fact that skating is most beautiful when it is purely about skating, the physical miracle that a human being can move faster than ordinary without unusual effort.

a performance this evening that was seven kinds of A-OK.
