At the end of the day it doesn't matter who likes/hates what.What matters is, does a particular band have an edge.In my opinion SOAD, RATM, Faith No More, Soundgarden even Dragonforce etc do.Nickelback and their ilk however play it too safe to be granted space on a metal fans forum.
Going back to the original thread which I appreciate i've joined a little late, I think mainstream American metal has done its best to hinder the development of global metal in general and I'll use the NWOBHM as an example.There was a time when Angel witch, Tygers of Pan Tang, Witchfynde etc were cutting edge both live and on vinyl, however when it came to the crunch and they produced their first albums, they were over produced, sounding too slick and polished principally to cater for the American market.Diamond Head were another example.Was it a coincidence that they disappeared after showing so much promise?
Thankfully the likes of Iron Maiden kept true to their roots and managed to survive.
I understand that Metallica nearly ended because they could't get any airplay due to the saturation of the media by the likes of Motley Crue and all the other cock rock crap.
I don't know if the American market is quite so important now, but imagine how the evolution of metal would have been affected if mainstream American music had maintained its stranglehold.Quite simply, I dont think we would have had any evolution.Thats why I've such an aversion to the likes of Nickelback.
