"Metal fans love a gimmick. From Kiss and Gwar to Gloryhammer and Evil Scarecrow – if there’s a costumed band pedalling an outrageous proposition, we jump all over it. The more ridiculous, the better. There’s a good chance this penchant for gimmickry is the cause of metal’s ever-increasing selection of bizarre subgenres, which carve out dedicated musical niches for pirate enthusiasts, gamers, and even Harry Potter fans. In fact, some of these subgenres are so niche, they’re only occupied by one band."
