A non-metal fan might give a listen to Euth’s release Demo 2015 and ask, “What are they screaming about?” To which I would answer, “Have you ever been to Laramie, Wyoming?” I kid, I kid. But there’s no question that smaller, remote towns where winter stretches on for months are often founts of extreme sounds — which is why Scandinavia and metal go together like chocolate and peanut butter. Not to say that Laramie is the next Sweden, but Euth delivers a Goth-inspired, chaotic ruckus that comes through loud and clear on songs like “Mercy Killing” and “A Knife Revealed.” Pack your earplugs and get ready for some elbows thrown in the pit as the Wyoming act headlines a four-band bill.
