Pick one. You can’t have both. :P
btw I am a huge fan of both Korn (they are the best-sounding act I have ever heard live, Daft Punk included) - and the psychedelic rock that is far more appropriate for such a festival, like MGMT, the Flaming Lips, Zeppelin, etc.
I’m just saying even though they were popular ‘rock’ acts at the time, I’d argue actually that these bands fall closer to the ‘metal’ and ‘nu-metal’ genres.
Regardless, Fred Durst literally told people to destroy shit, and they did.
