ok man, im from brasil and im gonna try to help you...
the biggest problem is: brasil is a very big country, im from the south, its really hard to cross the contry to go to other parties...
basicali every region have our own scene, the south scene, north scene, etc...
the biggsts scennes in the contry in my point of view are São Paulo and Rio de Janeiro at first place (southeast) Paraná, Santa Catarina and Rio grande do sul at second biggest scene(south), and goias at the 3th biggest scene (west).
if u gonna stay in south, i can help u a lot... im live in the north of Santa Catarina.
