It went unreleased for 20 years, but in the past couple months, Aphex Twin's Caustic Window has finally come to light. Fans contributed to Kickstarter for digital copies of the record, which later surfaced online. (Stream it below.) A copy of the album's ultra-rare test press recently went up for auction on eBay with a portion of the proceeds going to charity. The auction has ended, and wouldn't you know it, it went for a ton of money.

As FACT points out, the pressing sold for $46,300. The forum We Are the Music Makers, who initiated the Kickstarter effort, are voting on which charity will receive a portion of the auction winnings.

And remember: There are two other super rare Aphex Twin test pressings being auctioned.

Update: The A.V. Club points out that the auction was won by Markus "Notch" Persson, creator of the video game Minecraft.
