There seems to be some confusion about why we don't call speed metal "thrash" or "thrash metal" on this site.
The answer is that "thrash" is a separate genre. It's both metal and hardcore, a hybrid. From metal it got the riffs. From hardcore, the song structure and rhythm. The result is short barrages of intense sound that is both political like hardcore and meta-political; it criticizes society as a whole, not just its political aspects, much as how metal addresses the soul through experience.
Of the thrash bands, there were three major founders:Dirty Rotten Imbeciles (DRI)
)Corrosion of Conformity (COC)
In addition, there were others like dead horse
, Chronical Diarrhoea
, Fearless Iranians From Hell
I recommend studying this genre as part of metal's history, because it is both past and future. As society decays, more people need to look for the hidden truths that can be found once one stops believing social propaganda at face value. Things do not make sense as they are described.
Our future is in our own hands, and if we act on illusion, we may face the end prematurely -- or worse, doom ourselves to a tedious life of no achievement and a civilization based on hollow, shallow, tendentious values.
Recently, there has been a resurgence in thrash bands -- mostly on myspace -- and interest from fans. Republican administration + global warming + happy democratic propaganda = not happy youth. And when the youth finally get restless, there is often hell to pay.
