Hosting a metal show is a stressful prospect, even if it doesn't come with all the Satanic accouterments parents worried about in the '80s. For one thing, nothing else in rock 'n' roll makes noises quite comparable to metal's guttaral screaming and layered, loud guitars; for another, no other genre has thrown off quite so many warring, not-quite-compatible subgenres. Without the necessary experience, it's a constant battle to keep the bands audible and the diehard fans convinced you know what you're doing. Joe's Grotto has been around long enough to thread that needle, putting on doomcore and neoclassical shows with equal aplomb. It looks like a gritty, authentic venue, but it doesn't sound like a gritty, authentic venue, because it's got a great sound system. Lots of places periodically play host to Phoenix's metal-hungry music fans, but nobody does it more consistently and thoughtfully.
