It's a good album...definitely better than 'Hinterland' which is fairly uninspiring and lacks anything as memorable (or downright scary) as Demonique.
His 'best of' singles album 'Means of Production' is also supposed to be good. It has Demonique on it too!
I recently watched Halloween for the first time and I was listening out for the clips, some of which I recognised. So I think the ones used in the track are actually taken from two films: Halloween 1 & 2.
I'll have to watch the second one to be sure.
