Ok, there is the RARE solo in Nu Metal, that point has to be taken. Heck there's some stuff about an MP3 going round of a Bass Solo from Distrubted's Bassist, can't prove it's him, but still.
But it anit got shit on Myung's work either.
Scary thing is, after listening to Mudvayne's first album, if they had/used more musical skill, they'd be getting towards some low level form of Prog.
I guess it depends on what is considered "Nu-Metal"
I'm still not sure on what all bands are in that genre.
