Danish experimental folk outfit Efterklang returns with a new video for the opening track off of Piramida, their fourth studio album due in September on 4AD. Directed by Oodls (creative duo Jakob Steen and Christoffer Frandsen), the clip for "Hollow Mountain" is appropriately expansive, exploring sweeping natural landscapes via a series of photographs that hang from the beams of a rustic, wooden house. Added to the visual vocabulary are cryptic geometric symbols overlaid on the imagery. It all adds to up to a smart, semi-abstract, and very Scandanavian visual experience.
