The promise that Chicago art metal group The Atlas Moth displayed on 2011′s An Ache for the Distance is fulfilled in the forthcoming The Old Believer. A sprawling, visionary record, it balances moments of dark, brooding melancholy with fits of power and violence. It’s a stunner, vast in scope, and harrowing in tone. “Collider” is one of its more openly aggressive moments: it opens with a holler, before settling into a moody melodic passage, where icy piano twinkles beneath thick oceans of guitar. Throughout, the mood is turbulent, anxious, its restlessness made manifest in each slashing chord.
