Man, that show was incredibly heavy.
Tribulation was as good as I hoped they would be, and I loved SkeletonWitch. The new singer is the dude from Wolvhammer, and I thought he killed it. I picked up "Serpents Unleashed" and that has the old vocalist and it's currently blowing my mind as I work.
I know folks love High on Fire, but I wasn't feeling it. I think they were by far the most subdued of the bands - mostly stayed in place and played - which after 2 bands I needed more to keep me excited. I was starting to feel old and kranky by the time Abbath came on, and I didn't know if I would like them at all, but HOLY [big bad swear word], did they slay! I found myself drawn into a headbanging, screaming frenzy. I've been listening to Immortal now, and it's really good. Wish I had gotten a sweet Abbath shirt!
