Chicha is a type of Peruvian indigenous music that developed organically in the 1960's when the Amerindian population of the Peruvian Amazon was exposed to cumbia and American rock & roll. A great example of cumbia's ability to create hybrid genres, chicha music was performed on cheap electric instruments and electric guitars. A solid cumbia rhythm base was used to play Andean folk melodies in psychedelic style with lots of effects added into the mix.

Chicha and cumbia music is now quite popular in Peru, as you can see by these recent concert photos from flickr.
