Whatever happened to the high-pitched metal power screamer? There’s still a thriving metal scene today, but modern convention prefers a guttural demon burbling up from the mix. Demons can be high-pitched and piercing too! Like Rob Halford on “Painkiller,” a banshee swooping down at you from every angle, or Bruce Dickinson harmonizing with himself on “The Trooper” like an unholy Hadean chorus. I wish the style would make a comeback; when it comes to the low pitched guys, though, it’s hard to beat the vampiric gravitas of Glenn Danzig.
