Korn have a unique guitar sound caused by almost alarmingly loose strings. They fuse elements of grunge, punk, heavy metal, speed metal, folk music and hip-hop into their numbers. The band had 5 founding members:
Jonathan Davis - The frontman, singer and bagpiper. An American Scot whose heritage has led to use of bagpipes in the music and wearing of a kilt.
Fieldy - An unfortunately poor bass player.
Munky - A quite impressive lead guitarist.
Head - The rhythm guitarist. He has now, to the dismay of fans, left the band to use his music to propagate Christianity. (If you ask me, Christianity is doing just fine, but to each his own.)
David Silveria - The drummer, and a very talented one at that. When he auditioned to Head, Munky and Fieldy, he was mocked because he was so young; his skill impressed them to the extent that he was immediately accepted.
Korn have sold out more than once, and the result has been some godawful albums. They have, in the past, realised the error in their ways and returned to their roots.
Thrasher/Poptart: No. They suck.
I am avoiding the argument about Korn's musical quality.
