[Orb] towers of dub (perpetual twighlight of dawn mix)

Whilst hanging out with me mates in the {{++ultraworld++}} room I noticed that my newly acquired bootleg 'unidentified frequencies of orb' cd had this version of towers of dub on it. Where is this previously found? Where do these bootleg cd's actually provide something new? Are they just a ripoff. Who created them? Are any more significant than the others? For those not on soulseek lately, you simply must sign back on and see if we can't supply you with some interesting items (for 'sampling' purposes only of course).
