The Flaming Lips have long promised to release “blood vinyl” copies of their new collaborative record The Flaming Lips And Heavy Fwends. These copies of the album will include real, actual human blood from the band, as well as from collaborators like Ke$ha, Erykah Badu, Nick Cave, Chris Martin, and others. And now Wayne Coyne has Tweeted that copies will go on sale at the end of the week. A couple of catches, though: The blood-vinyl edition goes for $2,500, and only 10 copies will be made.

If you’re just hoping to hear this album, there’s probably a more convenient way to do it. But if you’re hoping to clone Erykah Badu, this will probably help a whole lot.
