The band’s backstory tells an imaginative tale of five dinosaur eggs (that were, of course, made of metal) surviving a mass extinction of some 65 million years ago. Witches who later discovered the eggs used their powers to hatch them. After that, the only thing left to do was make metal music for kids—and that’s precisely what Hevisaurus have done.
