After struggling to find their feet on 2015’s Node, pseudo-djent warriors Northlane have stunningly perfected their rebooted fusion of hyper-experimental prog rock and pitchurning metalcore on Mesmer. The guitars are heavier and more restless— Josh Smith nails the rhythm section with temperate baritone riffage, but lead axeman Jon Deiley is downright f***ing remorseless. Mesmer is the canvas on which the two wreak havoc: sepulchral bends flood the sullen Intuition, while Fade makes way for shimmering melodies and Solar shines with a wah-tinged groove. The cuts Veridian and Fade dip into a louder, flashier alt-rock vibe—a cleaner sound than we’re used to, but one that does not undercut their otherwise carnal shredding. The first half is marred by mundane jams, but made up for effortlessly by the second half.
