JAMs, one of KLF's alternate names, is short for "Justified Ancients of Mu-Mu." While it is not known for certain what the acronym KLF actually stands for, it has been suggested that it could be "Kallisti Liberation Front" (a reference to Discordianism, a modern chaos-based religion originally described by Malaclypse the Younger in Principia Discordia, but popularized by Robert Shea and Robert Anton Wilson in the Illuminatus! books, written between 1969 and 1971 that reverences the Greek goddess Eris aka Discordia), which the KLF do acknowledge.
Kallisti (meaning "for the fairest" or "to the prettiest", a reference to the Golden Apple of Discord the hero Paris was to award one of three goddesses: Hera, Athena & Aphrodite, and was said to have been the origin of the Trojan War) was also the ancient name of Santorini (aka Thera) in the Aegean Sea of Greece. The island is the site of one of the largest volcanic eruptions the planet has ever seen: the Minoan eruption (sometimes called the Thera eruption), which occurred some 3,500 years ago at the height of the Minoan civilization.
As The KLF, Drummond and Cauty pioneered the genres "stadium house"....releasing a series of international top-ten hits on their own KLF Communications record label, and became the biggest-selling singles act in the world for 1991.
From the outset, they adopted the philosophy espoused by esoteric novel series The Illuminatus! Trilogy, gaining notoriety for various anarchic situationist manifestations, including the defacement of billboard adverts, the posting of prominent cryptic advertisements in NME magazine and the mainstream press, and highly distinctive and unusual performances on Top of the Pops.
Re-reading Illuminatus! in late 1986, and influenced by hip-hop, Drummond felt inspired to react against what he perceived to be the stagnant soundscape of popular music. Recalling that moment in a later radio interview, Drummond said that the plan came to him in an instant: he would form a hip-hop band with former colleague Jimmy Cauty, and they would be called The Justified Ancients of Mu Mu.(JAMs or JAMMs)
"They travel the world in their ice cream van, they've voyaged to the bottom of time. They've been to the place where the Mu-Mu mate, and the children still cry 'Mine's a 99!'"
