Emma Ruth Rundle seems to have become an artist with a licence to shift around stylistically as much as she wants while still maintaining, and continuing to build, her devoted fanbase. Last year’s revered collaboration with Thou — May Our Chambers Be Full (Sacred Bones) was dense, heavy, aggressive and complex. Whilst everything Rundle turns her hand to shares a certain delicate and fragile emotional openness, Engine Of Hell (Sargent House) in most other senses explores the opposite end of the Emma Ruth Rundle sonic spectrum.
