The Amity Affliction Release Video For ‘Youngbloods’

taayoungbloodscover
Australian metalcore act The Amity Affliction have released a video for Youngbloods, the title track off their latest album, which came out last year. The album nearly won Australia’s Best Hard Rock/Heavy Metal award at the 2010 ARIA (Australian Recording Industry Association) Music Awards. The video is a pretty standard metalcore video with shots of the band performing in front of a crowd mixed in with shots of skateboarders. 
Can someone please explain to me why metalcore and skateboarding seem to go hand-in-hand so often?
