It was amazing. Favorite sets were The Rita, Paranoid Time, Gnawed and Aaron Dilloway. I'm not articulate enough (and wasn't sober enough) to write a good overview, but for harsh heads, there was definitely enough variation in styles to keep each next set exciting.
From what I saw, they were doing pro recording off the board and room, and they had multiple cameras. DVDr of the whole show sometime. My hope is that sound is mastered more like a tape than a live DVD.
