Great tracks! Sounds a lot like the british tribal popular in 92. I don't know these tracks, but (if you didn't already) you may want to stalk the following labels: Cowboy, Guerrilla, Limbo, Zoom, Stress, and anything in that vein.
Nice tracks. At around 1 minute into 5a it sounds like the tom toms (or whatever they are) from Underworld's "Mmm... Skyscraper I Love You". But that track wasn't released until 1993 - maybe a demo/remix version or something?
