Glad I saw this with Disciple as the opener, I think it worked much better than WPB which was the opener on last year's mini tour with Zombie. Except for Dead Skin Mask, I think Slayer's set list on the first few MayhemFests was great. I have long resigned myself to knowing that I am the only person who wants to hear anything off of Diabolus so I don't ever expect to.
3/8 - Tatesryche
