Ross Robinson reshaped heavy metal for a generation raised on the concrete-cracking beats of hip-hop and the mosh-ready riffs of hardcore. Reinventing thrash legends like Sepultura and molding nu-metal icons like Korn, the producer specialised in guitars that rattled your insides like a bass drop, funk rhythms flipped into battering assaults and primal screams disguised as hooks. But he also brought his precision-tooled rage to 21st century emo, sharpening the chaotic anthems of At the Drive-In and The Blood Brothers.
