COMMON ERA

Loud kei (ラウド系) is a Japanese "loud rock" movement that fuses the heaviness and aggression of metalcore, post-hardcore, and nu metal with the melody-first sensibilities of J‑rock/J‑pop and, at times, the theatrical aesthetics of visual kei. It is characterized by down‑tuned guitars, double‑kick drumming, breakdowns, and screamed vocals alternating with soaring, catchy choruses. Many acts weave in electronic elements (synth arps, EDM drops, vocoder/Auto‑Tune) and tight pop songwriting structures, resulting in music that feels both intensely heavy and anthemic. Live shows emphasize high energy, crowd participation, and a strong visual identity.
