What's that sound? Name that tune

I’ve been trying to ID this song ever since this mix was posted (almost 10 years ago, crumbs where does the time go?). I’ve heard a remix/remake of it somewhere, but still have no idea what the original is. I’ve contacted Pete Wiggs but no response, can anyone help? Would love to know what it is and to try and find a copy.

The song in question starts around the 49min mark on here Pete Wiggs — Test Pressing, fingers crossed :crossed_fingers:
