There's never really stopped being a multitude of local metal bands, either. One of my favorites right now is Phoenix-based blackened death metal band Six Million Dead.These guys employ two singers (one screechy, one guttural), breakneck percussion, and a fury of relentless, high-tuned guitars to produce the sound of a horde of demons slashing their way through a tornado. And that's more complicated to do than it sounds.
Six Million Dead are currently recording the follow-up to their 2009 full-length debut, Revelation at the End of Aeon. Hear their song "Odium" from that album below.
