Are a British electronic band who originated in Liverpool and London in the late 1980s. Scottish musician Bill Drummond and English musician Jimmy Cauty 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. As the KLF, Drummond and Cauty pioneered stadium house 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
