Innovators of the heavy metal subgenre we now know as nu-metal
or aggro-rock. Korn currently consist of 4 members now that rhythm guitarist Head has departed the band; Jonathan Davis, a great frontman and talented vocalist, Munky, a rather average guitarist (along with Head), Fieldy, a pretty slick bassist who greatly defines the band's sound, and Dave Silveria, an underrated and highly talented drummer. KoRn is known for their heavy sound, low-tuned guitars and dark themes and humour.
KoRn has many devoted fans around the world who love them for the music, not because of some poseur teen-angst image complex. It is because of these poseurs that many people hate KoRn, basing their opinion on the fact that many people who like the band shop at Hot Topic and suck at life, so the band must suck too. In reality, KoRn are respected by musicians as innovators, and famous because their sound simply kicks ass. KoRn acknowledges the fact that their recent albums have been sub-par due to wiggerism
and promises to return to their roots in their next album. Hey, at least they admit it and learn from it, unlike some bands who use the phrase "people don't like it just because it's different" as an excuse for their crapiness.
In conclusion, you don't have to like KoRn... just don't hate on them for stupid reasons. A lot of people think "real" metal bands like Iron Maiden and Lamb of God suck too, so keep that in mind when you bash them.
KoRn may not be the most technical band out there, but they are original and talented.
