Mark McGuire’s music is exploratory and adventurous. It’s got that same vibe of for-its-own-sake pursuit that’s associated with, say, the extreme climbs of long-dead alpinists, or hikers who hit the Pacific Crest Trail and the Appalachian Trail in consecutive years. This music seems less like a statement or a monument, and more like something done in cooperation with nature—a complement to something that already exists. This new EP is all interesting, but the two longer songs, “Noctilucence” and “Astral Protection,” really enchant.[BUY Noctilucence EP]
