-Korn
Korn's the band that basically helped define early nu-metal with their heavy focus on dark themes, low tuned guitars and bass, and occasionally rapped vocals. Around the mid-00s the band tried to go more in the direction of industrial influenced alt metal, and at one point even attempted a dubstep influenced album that had assistance from the likes of Skrillex and Noisia. Around the time their original original guitarist Brian "Head" Welch returned in 2013 (he left in the mid-00s, needing time away from the band to get clean off drugs) they went back to their nu-metal roots. Their latest album, The Serenity of Suffering, has been one of the band's most well received albums since Untouchables back in 2002.
