Nashville’s Those Darlins have been fine-honing their vision of garage rock by way of outlaw country for a few years now, and their upcoming record might be the most focused yet. Leadoff teaser “Oh God” finds the quartet scaling back the unhinged grit of 2011’s Screws Get Loose a bit, gathering around singer Jessi Zazu for an eerily open-ended cut, in which a voicemail message sets the stage for a murder ballad, lament or who knows what ominous next act on the LP, Blur The Line. Hear it above.
