To me, there's one heck of a difference between 'hard' and 'heavy'. I feel that DT makes mostly 'hard' music, with real 'heaviness' being more rare.
Good point, I think I know just what you mean, and it's helping me to further understand what people mean when they say ADToE is not heavy.
The
heavy stuff would be more like The Glass Prison and The Dark Eternal Night, whereas the
hard stuff would be more like The Root Of All Evil or even Behind The Veil. Would you agree with that comparison? Just want to see if we are on the same page.
By those standards, I do agree that ADToE is less heavy than it is hard. I guess I just feel like a lot of people pass it off as being neither hard nor heavy, and just being mellow or soft. I really think the album fits into the "hard" category though, as there are a lot of hard moments, especially in the guitar riff sections.
