In this January 22, 2018 photo, members of the Paraiso do Tuiuti samba school rehears their dances and songs, which make reference to Brazil's history with slavery, in the streets of Rio de Janeiro, Brazil. The samba school notes that Brazil is one of the world's most unequal countries in terms of income distribution, and that its top politicians and businessmen are predominantly white while more than 50 percent of citizens identify as black or mixed race.
