I saw the Summer Slaughter Tour 2008 (the American leg of the tour) and loved it. Born of Osiris, The Faceless, Whitechapel, The Black Dahlia Murder, and several local death metal/deathcore acts. The best modern death metal and deathcore music around, it was great. So much brutality. Unfortunately I did not get to stay for the entire thing because if I did, I would have died of dehydration and exhaustion. I spent all my money on a Despised Icon shirt and getting my friend in, then after that, I had no cash only a debit card, which they did not accept. And also you couldn't leave and return. So, I would have been at a 8 or so hour long death metal concert, moshing, throwing down, sweating everything, without water.
I would've died. Still a great show, I'll never forget it. Crowd surfed, throwind down, shook hands with the Faceless singer while he was screaming out stuff, all in all a great time.
