Even by Brazil’s ecstatic standards, the Boi-Bumbá of northeastern Brazil, held over three days in June, is a frenzied celebration. Retelling a local legend about the death and resurrection of an ox, the festival pits two rival samba schools against one another in Parintins’ vast arena, the Bumbódromo, which holds nearly 40,000 people. Every night the schools, divided into their rival colors of blue and red, try to outdance, outplay, and outdress each other in a spectacular 3-hour display complete with extravagant costumes, elaborate floats, and a steamy, joyful atmosphere.
Parintins Folklore Festival, or often also called Festival do Boi-Bumbá, Bumba Meu Boi, or simply Festival, is a popular annual celebration during three days in late June held in the Brazilian city of Parintins, Amazonas. Wikipedia
