well june is ''winter'' in brazil and peru

.
here in buenos aires we've already had Personal Fest and Southfest is coming up, but don't think they're really like european festivals
every year there seems to be a festival in Rio/Sao Paulo sponsored by a mobile phone company; either Claro or TIM, so could look out for those...but I don't think they're anywhere near June.
In April there's Abril Pro Rock in Recife, Brazil....but i doubt that helps ya
so yea, sorry i've been incredibly unhelpful
