When I hear Brazil, I think about incredible beaches, hot weather, good soccer team (although last world cup, it wasn't so), joyful people dancing samba, Gusttavo Lima's balada boa (we listened to that a lot on the radio last summer... checherereche is catchy haha), Río de Janeiro's Carnival, favelas, Sepultura (metal band) ...I must say I have never been to Brazil, although I would love to.
I hope that helps :)
