Chicha is a drink made from fermented corn. Its consumption can lead to you becoming very drunk. It is said that Chicha music is capable of doing the very same.
Chicha is Peru's equivalent of Tropicalía in Brazil or Afrobeat in Nigeria, a mix of traditional and Western styles. Chicha, which was generally referred to as Peruvian Cumbia until the 80s, is played in the 'rock band' format of guitar, bass and drums, though often with a multitude of Latin percussion instruments on hand, as well as keyboards (a practice which has grown due to their low costs and ability to create numerous sounds.)
