Roots of Knorkator

White Zombie was an American heavy metal band that formed in 1985. Based in New York City, they started as a noise rock band, releasing three EPs and one studio album in that style before changing to a heavy metal-oriented sound that broke them into the mainstream. The albums La Sexorcisto: Devil Music Volume One (1992) and Astro-Creep: 2000 (1995) established them as an influential act in groove metal and industrial metal, respectively. Their best-known songs include "Thunder Kiss '65", "Black Sunshine" and "More Human than Human". The group officially disbanded in 1998. In 2000, White Zombie was included on VH1's 100 Greatest Artists of Hard Rock, ranking at No. 56. As of October 2010, the band has sold six million albums, according to Nielsen SoundScan.
