that sounded very promising. I hear some Akercocke-esque guitar parts in there. The pre production demos sound really good too, they could almost just release those if they wanted.
They never disappoint - and get a load of Nergal's rack, damn - interesting to see he's using the Uberschall, I wonder what'll end up on the album (The Apostasy was Uberschall, Roadster, and his custom amp, though I don't know the ratios)
I think he's saying they're signature/indentifiably behemoth riffs or something. Kinda like the (R) for rights reserved (i think that's what it's for).
