More than any pop band in history, the KLF ripped off the music industry for a bucketful of loot and got away with it -- as illustrated in their own guidebook to creating number one singles, The Manual. Bill Drummond and Jimi Cauty applied the tactics of punk shock-terrorism to late-'80s acid house and became one of Britain's best-selling artists (recording also as the JAMS and the Timelords) just before their retirement in 1992.
