Yep: it's Carnival. For me a time to hibernate, and let the sambums have their fun ( only kidding sambums, we're pals).
Anyway, to prove that I am cool and also hip to the Carnival scene some Gilberto Gil has been made available below. The song would probably be heard during a Festa Junina instead of a Carnival celebration and I know what you're thinking: interesting, Festa Junina is far superior to Carnival and you are wise to notice. True, thank you.
