In 1968, in Iquitos, the capital of the Peruvian Amazon, a shoemaker named Solomon Sanchez decided to form a band with his five sons. They were the first band in the Amazon to play popular local rhythms with electric guitars. The new hybrid they were creating would go on to have an enormous impact on South American popular music. Some of their songs, such as Sonido Amazonico or Danza del Petrolero became the most emblematic of this new cumbia amazonica movement.
