None, it's an 'evolution'. I respect bands such as very early Korn, early Deftones, but those are spooky core, and not nu-metal like everyone likes to label them. I doubt if bands like Pimp Bisquit and Linkin Park would exist without those though. Oh and Korn is shit nowadays.
And there's also Prong of course.
the gathering are true influentials in their small genre though.bah its not like you must come up with the 8th note,the endeavour is to make your own sound at least.some spark
