The North Sea Scrolls play the Cabaret Voltaire on August 22 and 23 as part of The Edge Festival 11, the music strand of the 2011 Edinburgh Comedy Festival.
"Most inhabitants of these islands will, at some point, have contemplated their past or their present and thought, 'This can't be right'. It isn't'," the band biography read on the event's website.
"The truth, such as it is, is contained in the North Sea Scrolls, long a bone of contention among historians, theologians and people shouting at bins in car parks.
"Over the last few years, a triumvirate of unlikely questers has spent the time between tending their investments to seek the truth about these documents."
It continued: "They are Luke Haines, who has made many albums, Cathal Coughlan, who has made many albums, and Andrew Mueller, who has written two books.
"This dauntless trio have come to see themselves as seers of the runes, reluctant prophets - if you will - of arcane apocaltypticca. They are now ready to share the terrible knowledge they have disinterred. In song."
It concludes: "The truth is the scrolls. The scrolls are the truth. There'll be a brief quiz afterwards."
Tickets are available now and are priced at £12.50
Haines this year released his second memoir Post-Everything: Outsider Rock and Roll, the follow-up to 2009's Bad Vibes: Britpop and My Part in its Downfall.
The ex-Auteurs frontman released 50 unique volumes of his Outsider Music project in 2010 and played a final 'Volume 51' gig at London's Hoxton Pony earlier this year.
