Micaretas are off-season celebrations similar to Brazilian Carnival. The micaretas are similar to the Bahian Carnival and very different from the samba school parades that are popular in Rio de Janeiro. The central feature of a micareta is a large truck called a "trio elétrico." The trio elétrico is wired with loudspeakers and has a band performing on the truck's trailer. The truck drives slowly along the streets or sits parked in an enclosed space and a crowd follows the trio elétrico singing, dancing, and 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 the micareta, hires the band, sells admittance, and controls access.
