The KLF

The KLF (also known as the Justified Ancients of Mu Mu, the JAMs, the Timelords and other names) are a British electronic band who originated in Liverpool and London in the late 1980s. Scottish musician Bill Drummond (alias King Boy D) and English musician Jimmy Cauty (alias Rockman Rock) began by releasing hip hop-inspired and sample-heavy records as the JAMs. As the Timelords, they recorded the British number-one single "Doctorin' the Tardis", and documented the process of making a hit record in a book The Manual (How to Have a Number One the Easy Way). As the KLF, Drummond and Cauty pioneered stadium house (rave music with a pop-rock production and sampled crowd noise) and, with their 1990 LP Chill Out, the ambient house genre. The KLF released a series of international hits on their own KLF Communications record label and became the biggest selling singles act in the world in 1991.

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 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 (approximately £2.35m as of 2022).

The duo have released a small number of new tracks since 1992, as the K Foundation, the One World Orchestra, and in 1997, as 2K. Drummond and Cauty reappeared in 2017 as the Justified Ancients of Mu Mu, releasing the novel 2023, and rebooting an earlier campaign to build a "People's Pyramid". In January 2021, the band began uploading their previously deleted catalogue onto streaming services, in compilations.
