Richmond, VA heavy-hitters Inter Arma are full of surprises. Their full-lengths alone—2010’s Sundown and 2013’s Sky Burial—provide enough genre-bending, head scratching intrigue to occupy one’s time and mind, but couple that with the release of a 45-minute, single-track concept release, 2014’s The Cavern, and one can’t help but expect the unexpected from these guys. They play loud, fast and brutal, but they also play slow, soft and—don’t be surprised—brutal. Try to hold onto your hearing when the band shares a bill at the Caledonia with locals Savagist and Marses.
