Since reuniting in 2017, confrontational electronic pop duo the KLF have released a book and held a festival. Now, they’ve announced plans to build a pyramid of bricks filled with the ashes of 34,592 dead people. If you now find yourself asking, “Where do I sign up?,” you can order your brick—which will be filled with your ashes after you die—for £99 via their website. (“Buy now, die later,” reads the slogan.)

Construction of the pyramid is set to begin in Toxteth, Liverpool on November 23 (or “Toxteth Day of the Dead”) during a ceremonial event attended by the KLF’s Jimmy Cauty and Bill Drummond. According to the group’s announcement, “There may be other occurrences throughout the day and night.” There will also be free tea and mince pies.
