"100% Acidiferous" was founded in February 1993 by Marc Acardipane, Slam Burt, Fernando Sanchez & Patrick Vuillaume. It was run by Fernando Sanchez and Patrick Vuillaume.
The very first release from this label, which is known as 100%. The etching however, says 303-1. Mostlikely because the responsibles for this label were the guys from 303 Nation.
This on 500 pieces limited edition came on solid blue vinyl and only in a paper sleeve. Some of them even handnumbered. There is a problem with the tracklisting, because the stamp mentions "Warning" as the B-side track, while the actual track is "101 Scout". Maybe they changed the title later into "Warning", although that is very unlikely.
