In its isolated cities, cut off from the fashions of the capital, a unique style of music began to develop, inspired equally by the sounds of the surrounding forests, the roll of the mighty Amazon and Ucayali Rivers, and the rhythms of cumbia picked up from distant stations on transistor radios. With the arrival of electricity, a new generation of young musicians started plugging in their guitars and trading in their accordions for synthesizers: Amazonian cumbia was born.
Powered by fast-paced timbale rhythms, driven by spidery, treble-damaged guitar lines, and drenched in bright splashes of organ, Amazonian cumbia was like a hyperactive distant cousin of surf music crossed with an all- night dance party in the heart of the forest. While many of the genre's greatest tracks were instrumental, and others were simple celebrations of life in the jungle, the goal of every song was to keep the party going.
