An international metal supergroup featuring current and former members of Wales' Bullet for My Valentine, Canada's Threat Signal, and the United States' Still Remains and Throw the Fight, Kill the Lights emerged in 2019 with a sound that marries the relentless pace of metalcore with classic NWOBHM influences. Employing a muscular style built on a foundation of neck-snapping melodic metalcore that propagates huge anthemic choruses, the group began releasing punishing, hook-driven singles like "Shed My Skin" and "Plagues" in 2020. Their debut full-length album, The Sinner, appeared later that year; on the 2024 follow-up, Death Melodies, they developed a more cohesive identity.
