The KLF

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 New Musical Express (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 announced the KLF's departure from the music business and, in May of that year, they deleted their 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 or €2.75m 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 deleted catalogue onto streaming services, in compilations.
