Yeah, I think that comes out next week, or maybe this week. I'll definitely check it out, there's been no new bolt thrower material for at least a decade I'm sure
Edit: it does indeed say the 24th March at the end of the clip. It sounds no different to bolt thrower to me, although his voice is a bit more gruff.
I look forward to seeing them live, as I never got to see Bolt Thrower and they were a band that I really wanted to check out. They play a few Bolt Thrower songs looking at previous set lists, so that will be cool. They are also at summerbreeze this year
