Hi Eddie...

Well I had a good listen, and I mustn't be the expert I thought I was!! The only track I can properly ID is number 3, which is on the 'Tracks Couture' ep by DJ Rush (DJAX-UP-304), but it seems to be mashed up in the sampler - it must be Rush playing, cos much of the tracks seem to be looped and EQ'd heavily, which is very much his style.
Then theres a few tracks that sound alot like Kne' Deep stuff (Rush's label) - if you like that sound, you should check the back catalogue there... And some earlier Planet Rythmn records like Headroom's stuff I can certainly recommend...

Sorry i can't be more help =(

Best of luck with your hunting
