Meet HOWL, a Providence quartet who seek to ruin your face with their particular brand of devastating metal insanity. To that end, they’ve gone and gotten signed to the venerable Relapse label and assembled Full of Hell — a nine-song guided tour through a world in chaotic decline. Take “Heavenless”: its charge of feral drums comes at you like the Four Horsemen, then the guitars rear up and the ground gives way as Vincent Hausman’s hoarse, ungodly roar narrates the collapse.
