Newsflash;
If they're the headliners then they set the atmosphere, not the support band. Also if they're headlining then they're playing last. Just f**king leave the gig before they come on, genius.
ALSO: How you can criticise the vocals for Coheed and Cambria is beyond me when Madina Lake have the most generic, uninspired vocals I have heard in a long time. In addition, considering the "atmosphere" that Madina Lake and Fightstar set, not sticking to it would be a GOOD thing.
