They all look a bit different now. Not sure if that's a good thing or not
I think there was a lot of Anthrax type behaviour around that time, who invented it, who started it, I don't know but some of these guys were unsigned with little more than a few demos all playing the same stages. Anthrax did get lucky where as some of the others took a bit longer but I think the fact that there was more than just Anthrax makes it hard to make statements like we saw the other day when Blabber used the term "originators of the thrash/groove".
What's with the voice at the end of all those videos saying 'no one's seen this for 100 years', is that part of where the videos came from?
