Amazingly, this band hailing from São Paulo, Brazil have been around since 1983. Perhaps they are the first thrash metal band from Brazil. I haven't really listened to 'em much, only one or two songs off their MySpace. I was really impressed by 'em. They have quite a discography if you click on their name above. All of the other info is right there. I shocked I didn't know about 'em sooner.
I'm sure someone here might know 'em or wants to get into 'em. So uhhh yeah, that's all I gotta say.
