In the early 70 s a new sound grew out of the booming cities of the Peruvian Amazon. Chicha, as it came to be known, modeled itself on Colombian Cumbia music but replaced the accordion with surf guitars, and incorporated the psychedelic sounds of Farfisa organs and Moog synthesizers as well as Cuban Guajira,and the distinctive pentatonic scales of Andean melodies. Unlike other modern hybrids, such as Ska or Brazillian Tropicalia, the music never crossed international borders. This is the first ever Chicha compilation to be released outside of Peru.
