They actually used to be 'Tesox', who had a few great (for the time) records on Plastic City in the mid nineties.

I had a few Richley & Rivera records, but looking back they were more filler tracks than anything else. The B1 track on the Fiction EP (which is the one I think you're talking about Scott) is a cracker though..

I fished it out there a while ago, and will probably play it again sometime.
