Since the introduction of harsh vocals in heavy music, metal singers have tried to imitate the sounds of the animal kingdom, from the bark of a dog to the squeal of a pig. And although us humans have come close, nothing strikes fear in our primitive minds quite like the roar of an apex predator. Take for example the title track off of Body Count’s latest album Carnivore, which features the roar of a lion in the chorus, ripped straight from an internet video.
