a few items to address:
1. The reason Pure Hatred was so early was because they were playing certain selections from each album. I think they chose to play the 6 songs on Impossibility first in order to make people, like myself, think they were going to play the album all the way through. Also, they wanted to joke that after Pure Hatred that the set was over.
2. Cleveland has one of the best metal scenes in the country. The local bands thrive here. National bands play here all the time and love it because what's more metal than a depressed old industrial town in the middle of America with a crumbling infrastructure? It's pretty brutal here.
