History

Group
Eagle Soft Incorporated — Canada, founded 1982

One of ESI's earliest productions — released on 16 October 1986, predating both the famous #1 ESI-02 and #18 ESI-01 by several months. Only Black Angel is credited for graphics, with no coder or musician listed on CSDb. The October 1986 date places this among the very first ESI intros, from before Mitch and Scorpio established their definitive eagle-logo formula. Black Angel's contribution suggests an earlier visual identity existed before Scorpio's iconic eagle painting became the group's trademark. ESI was founded in Canada in 1982 — one of the oldest cracking groups in existence. This intro represents the group's formative period when their visual and musical identity was still crystallizing. The absence of the SID jukebox that would define later ESI intros indicates a simpler, earlier design philosophy.
