both. they started as a modernized 80's thrash band, then went nu-metal with The Revolting Room. However, it is quality nu-metal.

Quality nu-metal is usually bands that sold out. Sepultura, Skinlab etc. Bands like this retain good vocals and water down music slightly.

Bad nu-metal is...well, KoRn, Linkin Park, Limp Bizkit.

NEITHER KIND OF NU-METAL IS GOOD
