The KLF (also known as The Justified Ancients of Mu Mu (The JAMs), The Timelords and other names) were one of the seminal bands of the British acid house movement during the late 1980s and early 1990s.Beginning in 1987, Bill Drummond (alias King Boy D) and Jimmy Cauty (alias Rockman Rock) released hip hop-inspired and sample-heavy records as The Justified Ancients of Mu Mu, and on one occasion (the British number one hit single "Doctorin' the Tardis") as The Timelords. As The KLF, Drummond and Cauty pioneered the genres "stadium house" (rave music with a pop-rock production and sampled crowd noise) and "ambient house". The KLF released 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. The duo also published a book, The Manual, and worked on a road movie called The White Room.From the outset, they adopted the philosophy espoused by esoteric novels 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 at the February 1992 BRIT Awards, where they fired machine gun blanks into the audience and dumped a dead sheep at the aftershow party. This performance announced The KLF's departure from the music business, and in May 1992 the duo deleted their entire back catalogue.With The KLF's profits, 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 a million pounds sterling in The K Foundation burn a million quid. Although Drummond and Cauty remained true to their word of May 1992—the KLF Communications catalogue remains deleted—they have released a small number of new tracks since then, as the K Foundation, The One World Orchestra and most recently, in 1997, as 2K.
