In the realm of death metal, and old school reunion band could be a good fit for a headliner, perhaps...I'm thinking along the lines of a Cynic, Atheist, or Pestilence...something with that jazzy tech feel to it.
Man, I have eaten White Castle TWO times in my life and both times I got MAJOR ANAL BLAST!
(one time was actually when my band was recording in a studio!!! Luckily we were just doing vocals that afternoon....)
