Pain Jerk (Japanese; ペイン・ジャーク) is a NOISE music project run by Japanese musician Kohei Gomi. Pain Jerk was one of the more prolific and influential noise artists of the 1990s, and is one of the leading figures in the "dynamic" style of Japanese noise, alongside acts such as Merzbow and Kazumoto Endo. Gomi is also the owner of the noise label AMP, and a member, along with T. Mikawa and F. Kosakai of Incapacitants, of the noise supergroup Gomikawa Fumio.
