That's a mouthful.
Anyway, looks like they're a Finnish group and that title roughly translates to "War Cry Tournament, 2011".
Looking at the vids and not reading their website it looks like they use pvc, soft foam, and duct tape - really flexy weapons. At any rate, I dig their use of uniforms and the crowd participation. It would be epic if we could get our crowds to be so enthusiastic.
At any rate, enjoy.
