While recording There Is a Hell…, vocalist Oliver Sykes experienced horrifying night terrors that bled their way into the British band’s third album. Though the record is often despairing, and almost constantly pulverising, it’s also boldly inventive for metalcore: they use electronics, choirs and even an orchestra on the heart-racing “It Never Ends”. On top of that, the record features Canadian pop siren Lights singing hooks on “Crucify Me” and dubstep wizard Skrillex contributing vocals to “Visions”.
