The ones they played were just... boring. No sharp riffs, short and really quite formulaic solos, very little complexity. Not really very Nevermore-like songs at all. They had no "edge" whatsoever. Everyone sang along to 'Emptiness Unobstructed', especially the second time, but really no one seemed that interested.
That's always the danger when you tour an album that isn't out yet, of course.
I don't see them adding any more songs until the proper tour later in the year. Warrel wasn't really down with most of the lyrics, so I don't expect they've even rehearsed any of the others.
