During the 1970s and 1980s, he collaborated with filmmakers, playwrights, and musicians in further protest works against the dictatorship. Buarque approached the 1983 Concert for Peace in Nicaragua as a valid forum to vocalize his strong political views. Throughout the decade, he crafted many of his songs as vehicles to describe the re-democratization of Brazil. The Concert for Peace in Nicaragua was one in a concert series known as the "Central American Peace Concerts." These concerts featured various Latin American artists. The political turmoil that plagued this era were expressed in many of Buarque's songs. He later wrote "Budapeste", a novel that achieved critical national acclaim and won the Prêmio Jabuti, a Brazilian literary award comparable to the Man Booker Prize.
