Hailing from Utrecht in The Netherlands, Grey Aura create a liquid form of atmospheric black metal which shifts between forms like quicksilver, flowing over the boundaries of genres, slipping between cracks in the restrictive walls that surround them. Their second album, Zwart Vierkant, is breathtaking in its breadth and independence, dazzling in its ambition and utterly enthralling and all consuming in its complexity of vision. The collision of raging fury and romance within songs like ‘Sierlijke Schaduwmond’ is bewitching, the sweet, smoky jazz of ‘Parijs Is Een Portal’ is, as suggested, a doorway to another time, another world, another reality. The album is bound tightly to a novel written by Grey Aura’s Ruben Wijlacker which tells the story of an early 20th century painter who becomes obsessed with the Russian art movement, Suprematism, which idealises the abstract and rejects traditional artistic concepts.
