Special editions of the new Flaming Lips collaborative album will contain blood from the “fwends”.

The Flaming Lips have been assembling a release for Record Store Day titled The Flaming Lips And Heady Fwends and frontman Wayne Coyne has revealed that “five or six” copies will include blood that he has collected from the guests.

He told MTV “I don’t have everybody’s blood just yet, but I collected quite a few vials of blood and it’s actually sitting in my refrigerator as we speak… I’m going to try to take that same concept and put little bits of everybody’s blood in the middle of this record. Like a glass specimen thing.”

Coyne told NME that he has blood from Ke$ha, Neon Indian and Prefuse 73, and if he’s still collecting, then others on the album include Bon Iver, Chris Martin of Coldplay, Erykah Badu, Yoko Ono, Nick Cave and Lightning Bolt.

The Flaming Lips And Heady Fwends will be a double-album released for Record Store Day on April 21.
