Legendary duo announce return with three-day live event in Liverpool.

Legendary pranksters The KLF are making their return after a 23-year hiatus, and true to form, this will be no typical reunion tour.

The British electronic duo announced a mysterious three-day live event in Liverpool beginning Aug. 23. They will perform under their original name, Justified Ancients of Mu Mu, for Liverpool: Welcome to the Dark Ages.

The 400 tickets for the event quickly sold out after being released Sunday (July 23).

All attendees "will be expected to be volunteers," their website states.

It also comes with a warning: "The Justified Ancients of Mu Mu in any of their various past, present or future guises will not be performing music."

The KLF are best known for their "stadium house" early '90s hits -- including "3 a.m. Eternal," "What Time Is Love?" and "Justified and Ancient" -- and pranks like releasing a video of themselves burning a million British pounds and announcing their retirement on the stage of the 1992 Brit Awards after firing machine-gun blanks at the audience.

The titles for the Liverpool events are: "Day One: Why Did The K Foundation Burn A Million Quid?"; "Day Two: 2023: What The Fuuk Is Going On?" and "Day Three: The Rites of MuMufication."

The KLF also previously confirmed a book, called 2023: A Trilogy, will be released Aug. 23.
