From the outset, the KLF adopted the philosophy espoused by esoteric novels "The Illuminatus! Trilogy", making anarchic situationist manifestations, including the defacement of billboard adverts, the posting of cryptic advertisements in "NME" and the mainstream press, as well as unusual performances on "Top of the Pops". In collaboration with the Extreme Noise Terror at the BRIT Awards in February 1992, they fired machine gun blanks into the audience and dumped a dead sheep at the aftershow party. This performance pre-announced The KLF's departure from the music business and, in May of that year, they deleted their entire back-catalogue. Drummond and Cauty established the K Foundation and sought to subvert the art world, staging an alternative art award for the Worst Artist of The Year, and burning one million pounds sterling.
