One of the major expressions of this "resistance samba" in the first half of the 1960s was Zicartola, a bar opened by sambista Cartola and his wife Dona Zica in 1963. which transformed in a short time at a famous meeting point of veteran sambistas, attracted the attendance of many left-wing intellectuals and students, and became famous for its samba nights that, in addition to revealing new talents, such as Paulinho da Viola, revived the careers of former composers then ostracized from the music industry. In February 1964, the year of the Brazilian military coup d'état, it was released the Nara Leão's debut album, which included sambas by traditional samba composers such as Cartola, , Nelson Cavaquinho and , as well as samba songs from the bossa nova nationalist branch. And at the end of that year, Nara Leão met with Zé Kéti and João do Vale for the musical Show Opinião, which became a reference as an artistic manifestation in protest to the authoritarian regime established.
