He and his wife, Joan Jara, were key participants in a cultural renaissance that swept Chile, organizing cultural events that supported the country's new socialist government. He set poems by Pablo Neruda to music and performed at a ceremony honoring him after Neruda received the Nobel Prize in Literature in 1972. Throughout rumblings of a right-wing coup, Jara held on to his teaching job at Chile's Technical University. His popular success during this time, as both a musician and a Communist, earned him a concert in Moscow. So successful was he that the Soviet Union tried to latch onto his popularity, claiming in their media that his vocal prowess was the result of surgery he had undergone while in Moscow.
