Duo comprised of Jimmy Cauty and Bill Drummond. Cauty was born in Devon, England; Drummond was born in South Africa but grew up in the Dumfries & Galloway area of Scotland. KLF 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. Their most notorious performance was a collaboration with Extreme Noise Terror at the February 1992 BRIT Awards, where they fired machine gun blanks into the audience and dumped a dead sheep at the aftershow party.
