Harsh noise is a subgenre of noise music that emerged in the early 1980s, originating from the Kansai no wave movement and later Japanoise, primarily through acts such as Merzbow, Hijokaidan, Hanatarash, C.C.C.C. and Incapacitants, and was further developed by the European power electronics scene and American noise musicians such as the Haters, Daniel Menche, and Richard Ramirez.

Harsh noise is an extreme subgenre of noise music characterized by its rejection of music theory and traditional song structure, with little or no conventional melody, rhythm, or harmony. Artists typically employ effects pedals, synthesizers, manipulated recordings, or custom-built electronics to generate distortion and feedback, resulting in compositions of dense static, electronic screeches, and abrasive sonic bursts. Performances often incorporate improvisation, and the style is frequently described as inaccessible and lacking commercial appeal. Harsh noise is primarily associated with underground music, with regional scenes emerging internationally in Japan, England, Canada, Indonesia and America.

History

1980s–1990s: Origins

During the 1980s and 1990s, harsh noise music originally emerged in Japan through the Japanoise scene, which grew out of the Kansai no wave movement. Early Japanese noise acts such as Merzbow, Hijokaidan, Hanatarash, C.C.C.C. and Incapacitants would prove influential in establishing the sound of harsh noise.

Harsh noise wall

Harsh noise wall (also known as wall noise, noise wall, or HNW) is a subgenre of harsh noise that emerged in the 1990s. originally pioneered by artists such as Richard Ramirez, Skin Crime, the Rita and Vomir. Music journalist Russell Williams described the genre as "a literal consistent, unflinching and enveloping wall of monolithic noise".

Harsh noise wall features noises layered together to form a loud, distorted, brickwalled static sound. French harsh noise artist Vomir described the genre as "no ideas, no change, no development, no entertainment, no remorse". Harsh noise wall musician Sam McKinlay, also known as The Rita, considered the genre as "the purification of the Japanese harsh noise scene into a more refined crunch, which crystallizes the tonal qualities of distortion in a slow moving minimalistic texture."

Gorenoise

Gorenoise is an offshoot of goregrind and noisecore that abandons rock-based sounds for harsh noise. New Noise Magazine characterized the genre as drum machines "hammer[ing] at 1,000 BPM over top of gurgling pitch-shifted toilet vocals". The band Anal Birth is credited as one of the progenitors of gorenoise. and Melanocytic Tumors of Uncertain Malignant Potential.
