Slayer is the reason I will be going. Slipknot is fun but I've seen them 3 times already. I've seen Slayer 3 times too, but they are also one of my favorite bands. And I've seen Anthrax twice now and saw High on Fire with Dethklok/Mastodon. I will be going on beer runs during all the bands outside of those 4 (and the special guest of course if it's Motorhead or someone else good).
