Call them post-metal, call them sludge, call them post-hardcore—whatever you do, honor their heaviness. These hard-hitting musicians from Belgium find a balanced, meditative sound at the intersection of all things metal, channeling an intense spirituality into their kaleidoscopic hard rock. Since 1999, their music has paired relentless guitar riffage and maniacal drums with introspective synths and long stretches of dissonance. Having formed the Church of Ra as a collaborative umbrella for likehearted bands such Oathbreaker, Amenra has cast an ethereal web of distortion that reaches far beyond their home in Flanders.
