GISM was a Japanese mid-paced hardcore punk band (with heavy metal influence) formed in Tokyo, Japan in 1980. The acronym GISM stood for many different variations, they include: God In the Schizoid Mind, Guerrilla Incendiary Sabotage Mutineer, General Imperialism Social Murder, Genocide Infanticide Suicide Menticide & Gnostic Idiosyncrasy Sonic Militant. The band initially composed of: vocalist Sakevi Yokoyama, guitarist Randy Uchida, bassist Kannon, & drummer Hiroshima. Randy Uchida often used heavy metal style guitar solos & riffs, nonetheless, GISM were one of the first Japanese hardcore bands, while at the same time drawing much influence from the early industrial/avant-garde music scene; something extremely uncommon in punk bands at that time.
GISM has attained a cult status in the international punk scene, duly for their unique blend of heavy metal and hardcore punk. Several bands emulated the vocal style of Sakevi Yokoyama, who is well known for his low pitched vocals, which was very uncommon during the early 1980s.
Randy Uchida & Hiroshima also played with Ronny Wakamats & Michel Hammer in a side project R.U.G. (Randy Uchida Group), which released an vinyl EP entitled "Deathly Fighter" in 1984. Kannon also played bass for female fronted band Front Guerrilla which released an EP entitled "Fight Back" in 1986. Kiichi Takahashi was the vocalist for occult heavy metal band Sabbrabells.
