Nu metal originated with one band and one band only: Korn. Just as definitively, it was one album - their pioneering self-titled debut - that set, nay created the scene.
Although spoken about like herpes in 2009, nu metal was actually vital in democratising musical ability after the shred-happy 1980s. By the mid-1990s, downtuned grooves and angst were in, sweep picking and falsetto were out and nothing distilled it more than this Bakersfield five-piece.
The style got old, fast and Korn never quite equalled their 1994 debut but it's easy to forget just how startlingly original it was at the time.
Fact: that there would certainly be no Slipknot if it hadn't been made.
