We’re excited to announce that the Series Four exclusive release will be Navhalr’s S/T Double LP 

NAHVALR is the world's first open-sourced black metal project. Spear-headed by Dan Barrett and Tim Macuga (of HAVE A NICE LIFE), NAHVALR aims to create the densest, most visceral sounds possible by combining the input of a dozen collaborators, all working individually, in a coherent and intuitive way. In other words: several people, operating anonymously around the globe, have their work hacked, chopped, distorted, fused and recorded over to create something altogether new.
