DARK MTNS, a.k.a. the tandem of Zack Robbins and Josh Mackie, has a new album, Up Above This Cloud, out now via Dub Sum. Grounded in harmony-stitched melodies, the collection of songs projects an effervescent glow. However, one can pull back that folk surface to reveal a murkier, hard-churning sense of complex and, at times, chaotic terrain. Wade into its reassuring, shoegaze-y waters.
