'''Voice Crack''' was a Swiss electronic [[free improvisation]] band. Formed in late 1972 by Andy Guhl and Norbert Möslang, Voice Crack began as a  [[free jazz]] duo. Then they used pre-recorded tape effects and live sound processing. By 1983 they had eliminated normal instruments in favor of what they called "cracked everyday electronics". This included "radios, turntables, transmitters, dictating machines" and other items that are cracked open and manipulated to produce "new sounds using magnetic and radio waves in a complex system controlled by movements of their hands and by light."<ref>[http://www.for4ears.com/poire_z/about_poire_z.html For4ears.com] {{webarchive|url=https://web.archive.org/web/20120716234951/http://www.for4ears.com/poire_z/about_poire_z.html |date=2012-07-16 }}</ref> 

The result consisted of buzzes, clicks, drones, and oscillations. [[Erstwhile Records]] described it as "cascading magnetic waves" that "arc across the sky as three-headed critters race and rummage through alien flora."<ref>[http://www.erstwhilerecords.com/catalog/reviews/011_review.asp Erstwhilerecords.com] {{webarchive|url=https://web.archive.org/web/20040423150448/http://erstwhilerecords.com/catalog/reviews/011_review.asp |date=2004-04-23 }}</ref> Voice Crack's work was favorably compared to some of [[John Cage]]'s.

Voice Crack collaborated with [[Borbetomagus]] and [[Butch Morris]] and were members of [[poire z]]. The group disbanded in 2002.<ref>[http://andy.guhl.net/portrait/ Andy.guhl.net]</ref>
