What is "chirigota"

Chirigota is a genre of Spanish choral folksong originating in the Province of Cádiz. The songs are satirical in nature and are performed predominantly in the streets by costumed performers during the annual two week carnival. It has been described as a vehicle for gossip and public comment, especially of a political or moral, and sometimes prurient, nature. Suppressed during the Franco dictatorship, along with carnival in general, there has been a massive resurgence of the art-form since his death and the re-establishment of democracy.
