The KLF welcomed 2021 by putting a collection of their ’80s and ’90s hits, like “3 AM Eternal” and “Justified and Ancient,” on streaming services for the first time ever. They’re doing a little more looking back with a new documentary, Welcome To The Dark Ages, which is out now.Directed by Paul Duane, the film looks at KLF conspirators Bill Drummond and Jimmy Cauty’s “Welcome to the Dark Ages” festival they put on in Liverpool back in 2017, as well as their plan to build The People’s Pyramid which is made of bricks containing ashes of dead people.
