右も左も支配する頭は今日も肉を食いヨダレを垂らす。

Japanoise is an extreme, experimental branch of noise music that arose in Japan and became known for its overwhelming volume, dense timbral saturation, and improvisatory intensity. The term was popularized by Western writers to describe a constellation of Japanese artists who pushed noise to visceral, physical extremes. Rather than melody or harmony, Japanoise foregrounds texture, feedback, distortion, and the live manipulation of electronics, contact mics, metal objects, and effects chains. Performances often emphasize spontaneity, risk, and theatricality, ranging from static, crushing walls of sound to frenetic cut‑up barrages.

Rock is a broad family of popular music centered on amplified instruments, a strong backbeat, and song forms that foreground riffs, choruses, and anthemic hooks. Emerging from mid‑20th‑century American styles like rhythm & blues, country, and gospel-inflected rock and roll, rock quickly expanded in scope—absorbing folk, blues, and psychedelic ideas—while shaping global youth culture. Core sonic markers include electric guitar (often overdriven), electric bass, drum kit emphasizing beats 2 and 4, and emotive lead vocals. Rock songs commonly use verse–chorus structures, blues-derived harmony, and memorable melodic motifs, ranging from intimate ballads to high‑energy, stadium‑sized performances.
