Megalithomania! was an official CD-R release by Coil limited to a pressing of 230 copies, 123 of which were available in their box set The Key To Joy Is Disobedience. It is a live recording of their performance at the Megalithomania festival at Conway Hall in London, England.
According to the credits, "Coil were: Jhon Balance, Peter Christopherson, Thighpaulsandra, & Ossian Brown with Pierce and Massimo. Sound By Danny Hyde."
This performance consists of an extended performance of only one song, "The Universe Is A Haunted House", which has never been released as a studio version. Another live version of the song appears on Live Four; it is also listed on "CD B" of Live One, although it is actually the same track as "Blue Chasms".
This release does not have a catalogue number.
