Chicha started out in the late 60’s, in the oil-boom cities of the Peruvian Amazon. Cumbias Amazonicas, as they were first known, were loosely inspired by Colombian cumbias but incorporated the distinctive pentatonic scales of Andean melodies, some Cuban guajiras, and the psychedelic sounds of surf guitars, wah-wah pedals, farfisa organs and moog synthesizers. Chicha, which is named after a corn-based liquor favored by the Incas, quickly spread to Lima.
