You want to go to a show full of scene kids? It's not a hardcore festival at all. Maybe year one and somewhat year two but this year? AFI, HIM, Taking Back Sunday, My Chemical Romance, Paramore, Dance Gavin Dance, Four Year Strong, Placebo, Shinedown... yuck.
Outside of It Dies Today, Anti-Flag, Devil Wears Prada, Emarosa, Comeback Kid and Enter Shikari I have no interest in it at all. And I definitely don't like any of them enough to pay $100+ to see them.
Compare that to last year with In Flames, Every Time I Die, Unearth, 36 Crazyfists, Evergreen Terrace, Alesana, Underoath, All That Remains, Horse the band, Amity Affliction, House vs Hurricane... then the year before it they had Killswitch, Thursday, As I Lay Dying, From Autumn To Ashes, Shadows Fall, Haste The Day, Still Remains, Bleeding Through, Carpathian, Amity Affliction, Break Even, Anime Fire... whether you like the line-up this year or not there is definitely a shift in the sort of bands they are bringing over. There's no way it's a hardcore festival this year though regardless.
Everyone has their own tastes but I have no idea how you can say it's not a metal festival. There's more metal bands this year than ever. If they are going to start bringing over less hardcore bands I'd much rather they get metal bands over garbage like Paramore and My Chemical Romance.
