Revelers participate in the “Carmelitas” street parade in Rio. “Carmelitas” is a band started in 1990 by a group of friends who gathered for soccer and drinks just outside a Carmelite convent. Jokes about the possibility of nuns escaping to join the party gave rise to the band, which parades twice: once at the beginning of Carnival and then on the last day.
