I found this gem on /r/lostwave. It's supposedly an 'unknown test pressing'. The instrumental sample is The Sylistics - People Make The World Go Round and is from the 1990s. The background behind it and the artist it belongs to is unknown.
What commenters claim it sound similar to: Mos Def NWA Bahamadia Paula Perry Lin Que
Theories/leads: The song must be after 1993 as it mentions the World Trade Center bombing. Second singer sounds of Jamaican descent. Recording quality suggests the artists had access to a recording booth, maybe had money, ties, or already known in that sphere. Sounds like Crompton/LA underground.
