HOLY SHIT!!!!!!!!!!!!! I never thought that could happen again!!!! it's by far their best effort!!!!
Someone MUST record it on video!!!!!
Edit: as I said on the another Inferno thread, it's great that Borknagar play there and I were really looking forward for it (even if I can't attend the gig), since it's the 10th edition of a festival started by a Borknagar member. That's something people should know better.
I wonder if Borknagar will record it this time to a future release, the guys are playing incredible live and I think it's a wonderful chance to get an impressive material for a DVD or at least to be bonus material on the next album.
