Tropicália or Panis et Circencis, released in 1968, is a concept album because it integrates Tropicalist aesthetics and language into its corpus. With its twelve songs, from start to finish, it constitutes a kind of anthropophagic ritual of high devouring, in which the relics of Brazil, represented through cultural, political and social myths, reinforce the intention of suturing the consolidation of the past, present and future of the Brazilian nation.

It is also considered dialogical and polyphonic, as the dissonant but collective voices, arrangements and compositions by Caetano Veloso, Gilberto Gil, Gal Costa, Capinan, Tom Zé, Os Mutantes, Torquato Neto and Rogério Duprat reference Oswald de Andrade's Anthropophagism, Glauber Rocha's Cinema Novo, the artistic expressions of Hélio Oiticica and Rubens Gerchman, as well as pop art and national and international counterculture. However, it is an album-object that invites the viewer to activate all the senses, synesthetically, because, in the plurality of the universe of each song, there is something to be read, seen, felt and, possibly, transformed, so it became the manifesto of the Vanguard Movement, whose ideologies transformed MPB.
