Best Opener I've seen: Very close between Disciple by Slayer,[sic] by Slipknot and Sonnet by Rammstein. Honestly can't decide between them.
Best Closer I've seen: Bury Me In Smoke by Down.
Best Opener I want to see: Suicide Note Pat. I and II by PanterA, but of bands still around, Diamond Eyes by Deftones or Aces High by Iron Maiden.
Best Closer I want to see: Octavarium by Dream Theater.
Yesterday don't mean SHIT.
