Behemoth are putting it all on the line for their new album The Satanist, pouring a lot of blood and sweat into its creation, literally.

According to Heavy Mag out of Australia, the artwork template for the album will include the blood of Behemoth lead singer Adam “Nergal” Darski. the Polish black metal band has not recruited famed platelet painter Vincent Castiglia for the project. However, they’ve enlisted Russian Symbolist painter Denis Forkas. Heavy Mag says Nergal delivered a box containing his blood to Moscow where Forkas then mixed the blood into the paint.

“I wanted to incorporate some of my DNA into the art,” Nergal told the publication. “This album seems to be so defining of who we are now as people and as individuals, and considering all the instances in recent years, [we wanted] to make it more ‘ours’ than it is usually.”

With a few minor complications along the way, including a producer switch from the Evangelion album-credited Colin Richardson, The Satanist release has been pushed to 2014. Slayer, Hatebreed and Children of Bodom producer Matt Hyde took over production after the band cited creative differences with Richardson. As far as decisions on packaging and artwork, Nergal apparently took a strong hold on that one. How he extracted the blood for the record is still unclear.
