He performed as a singer and guitarist the 1960s as well as writing a play that was deemed dangerous by the Brazilian military dictatorship of the time. Buarque, along with several Tropicalist and MPB musicians, was threatened by the Brazilian military government and eventually left Brazil for Italy in 1969. However, he came back to Brazil in 1970, and continued to record, perform, and write, though much of his material was suppressed by government censors.
