After a week which saw digital backers on Kickstarter receive the previously unreleased Caustic Window, some even rarer Aphex Twin records have surfaced on Ebay, on vinyl and having never been played.

Melodies From Mars is a collection of unreleased material intended for 1999, which only saw the light of day through cassettes distributed among Rephlex's staff and close friends. you can bid for that here. Analogue Bubblebath 5 is an intended 1995 release that never got officially released with only a very few Rephlex customers attaining a physical copy. You can bid for that here.

Check out Caustic Window below, and if you're still interested in purchasing that one you can find it here.
