From WFMU’s Beware of the Blog:
Jud Jud was the band that was too straight edge for instruments. Every song (including their “tuning”) on their 1989 seven Inch The Demos consists of Steve Heritage (in the left stereo channel) and “B” (in the right channel) chanting their manifesto, which consists mostly of the word Jud, as well as occasional feedback and explosion noises. But mostly the word Jud. Repeated over and over again. The Demos contains pictures of fake flyers for Jud Jud headlining over bands like Minor Threat, which never happened. But the hoax/parody worked remarkably well.
