Cannibal Corpse's music has been banned in Australia, banned in Germany, and banned in Russia for its gruesome content and gory cover art. Still, Cannibal Corpse is the top-selling death metal band of all time, with two million combined sales of all its albums. Originally from Buffalo and now based in Tampa, Florida, Cannibal Corpse is the heaviest of all death metal bands. It's an indiscernible sub-baritone shriek that makes it rather hard to sing along. But if you can take the thundering volume, it's a rather cool spectacle.
