The micaretas are similar to the Bahian Carnival and very different from the samba school parades that are popular in Rio de Janeiro.
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.
A bloco is an enterprise which obtains permission to participate in the micareta, hires the band, sells admittance, and controls access.
The first micareta took place in Feira de Santana, the second largest city of the state of Bahia.
