But, decades before ...
Loud, pounding drums; harsh, whispered vocals; unusual instrumentation; and a somewhat catchy tune buried underneath. That old-timey bit at the beginning? That's sampling. Caledonia by Cromagnon has all the staples of modern industrial music (minus the angsty lyrics), and it came out way back in 1969.
What makes this even eerier is that the band released that one album and then simply vanished. As the legend goes, Brian Elliot and Austin Grasmere were two average pop musicians who got tired of writing non-insane music and decided to try something a little different (meaning, something completely insane). Calling themselves Cromagnon, they hooked up with a hippie commune called the Connecticut Tribe and recorded an album titled Orgasm.
But you could probably tell that from their cover art.
The album never really made any headway, and no one paid attention to the damn thing until 2000, when it was reissued as Cave Rock, which is probably the biggest step down in titles since Puff Daddy became whatever the hell he's called now.
If Gary Larson did the cover art for a prog rock album, this would be it.
