Every December, Natal has the Carnatal, the best carnival out of season of the world. With bands such as: Chiclete com Banana, Asa de Águia, Cheiro de Amor, etc. Having thousands of tourists, artists and many famous people in four days of pure fun. Carnatal is different from the samba school parades, popular in Rio de Janeiro. Carnatal is something like this: During the days of party, a huge truck (called "trio elétrico"), with a band on the top and sound boxes all around, drives slowly along the streets. The crowd follows the trio elétrico singing, dancing, jumping to the sound of the music. To be allowed to follow the truck, one must buy admittance to one of the several "blocos" (block). A bloco is an enterprise which obtains permission to participate in Carnatal, hires the band, sells admittance and controls access.
