what's the metal capital of South America?
São Paulo
And it's not cause I live here. It's just where stuff happens. Biggest city in half the globe though, so it's not a big surprise.
I dunno if exactly Sao Paulo, but yes, it must be one of the big cities in Brazil.
And about that video: are we debating the type of fans? if so, i can assure you that the only reason why they come here (besides money, of course) is cause we have an insane crowd.
Too bad this is not a metal country, it's a "rock 'n roll" country... that's why The Rolling Stones are gods over here.
