I went to this on the weekend:
Best extreme underground gig Australia has seen in years, so good. Unfortunately was in a blackout for the first night and remember nothing, but the second night was sober and it was awesome. Hellbringer and Assaulter stood out the most, Hellbringer sound like Slayer, Sodom, etc, Assaulter has ex-Destroyer 666 member and is similar in lyrical and musical style yet very much their own sound. Sick sick gig.
