Going through a crate of a friend's vinyl, found a promo that is not familiar at all, and trying to indentify it. All I have to go off of is the etching: CSI 10 A-01-1-1 / CSI 10 B-01-1-1; and the store sticker that just has CSI-10 PROMO 2X12. Can not find the second plate though, and the first plate just gave a quick listen, sounds like late 90s/early 00s dnb. Any ideas? Tried the database here & on Discogs.
