What Kraftwerk was to electronica, Colourbox (and later MARRS) and the KLF were to the art of sampling:
Colourbox, "Hot Doggie" Lonely Is An Eyesore 1987 compilation by 4AD records, who also basically invented Goth music with Bauhaus in 1980 and were probably the most amazing record label ever to exist until, alas, they got sold to Capitol/EMI in 1991. They also brought the world The Pixies.
MARRS, Pump Up the Volume
Which brings us to one of the most influential bands in modern history that most people know nothing about, the KLF:
"Justified and Ancient" feat. Tammy Wynette:
They also wrote the Manual, or How You Can Have a No. 1 Hit Without Really Trying

And then they played a heavy metal version of "3 a.m. Eternal" at. The Brits (UK verse of Grammys) with the pair spraying the crowd with blanks from M-16s, causing attendees to go diving under tables and such. The video doesn't do it justice.
As the curtain lowers, the PA announces, "Ladies and gentlemen, the KLF have now left the music business." They also left a slaughtered sheep with the band's logo outside the official after party. More punk rock than faggoty outfits like Metallica, who just sued their fans and ruined Napster.
