Behemoth will crush all again, looking forward to hearing the new material live.
I thought JFAC's Doom EP was over-rated, but Genesis had it's moments and the new album Ruination is their most technical and death metal sounding release to date. Although they may be somewhat generic, they were actually pretty kick arse live when they toured here a couple of years back (hence why they're in the line-up, I assume).
While they might help pull extra numbers, I think Behemoth's current sound would probably appeal to some JFAC listeners and, given their current popularity, wouldn't be surprised if a few of them are fans already.
Good to see Goatwhore in there too, know they've been around for ages although still haven't heard much of their material as yet, but it's great to see more underground bands given the opportunity to come out to Australia on these tours.
