I don't understand the headliner, but I'd love to see those other three bands! White Wizzard killed it when I saw them and I forever regret not seeing BBB before their old singer left. Vektor I'm sure would be great live (though I like the other two bands better).
12/17 - Gorguts (?)
2/16 - Children of Bodom/Death Angel (?)
