Hellsingi Metal Festival

You wouldn't be able to tell from the band's name, but Heaven Shall Burn is a group that sings about staunchly opposing racism and fighting social injustice, including animal rights, veganism and political corruption. Calling their death metal infused hardcore music "Deathcore," the German band's members are ferocious supporters of equal rights and threaten bodily harm (lyrically speaking) to anyone who dare oppose them.
