wikipedia.org: "Analord is a series of 12" vinyl recordings by UK-based electronic music artist Richard D. James. The first installment, Analord 10, went on sale through the Rephlex Records website on December 15, 2004, and was packaged in a leather binder with sleeves for housing the rest of the series. The record was marketed under James' primary alias "Aphex Twin", although subsequent Analord recordings have so far been released under the "AFX" pseudonym.
There is a condensed, album-sized version of the series titled Chosen Lords." More info
