Leave Limp Bizkit to the 15 year old kids who think they hate their parents. Inevitably, the loud guitars and screaming vocals will somehow lead them to entry level metal bands (perhaps even Metallica or Megadeth types). Most likely the ones from the scenes eminating out of the northeast that have tons of CORE. From there, I imagine that at a show or party, these kids will hear a band with no core, but maybe a bit of DEATH...thusly they will be lead down the path of generally superior music.
If we're lucky, they will then take it upon themselves to search out older bands of their chosen METAL genre. Of course, this then puts them on the trail of other great bands and genres. Natural evolution I figure. Pure musical bliss results.
