Sex can refer to three known artists: 1. Sex is a 1960's fuzzy psych-rock band. A French-Canadian band from Montreal, Quebec, whose lyrics are English. They releasd two albums. Both albums are ultra-rare and the music is comparable to Elias Hulk or Ellison with sledgehammer drums, furious fuzzy lead guitar and wasted vocals. By the second album the group had expanded to a four piece and become a little more progressive but still were as heavy as hell.
