This is a superb 3 disc set. The 12" and 7" play at 45rpm but the 10" plays at 33rpm. Most of the tracks are in your face pounders similar to UI Red but personally I think these sound better as there's more going on. Particularly with the relentless percussion. The 12" has one rather uninspiring track that sounds like a dodgy slap bass funk thing, not really in keeping with the rest of the music. The second track on the 7" is beatless and is just soaring synth noise kind of like whale calls.

This set is generally attributed to being Richard D James (Aphex Twin) under the production guise of Tan-09.

The 'We are the music makers' website goes on to suggest that he is responsible for the 12" and 10" but the 7" is Grant Wilson-Claridge (Co-founder of Rephlex records).

The 'All Music Guide' website also states that James produced the 12" and 10" but attributes the 7" to Mike Dred (Kosmic Kommando) who is also rumoured to have produced UI Blue and UI Yellow.
