Tropicalia, or Tropicalism, is one of Brazil's most significant cultural movements. Born in the late 1960s by a collective of like-minded souls, it used music and visual arts as a voice to confront the cultural and political establishment. This vibrant feature documentary explores this iconic and era-changing time in Brazil's history with material lovingly gleaned from the archives, stunning images, and the testimony of the group's protagonists including Caetano Veloso, Gilberto Gil, Tom Ze, Arnaldo and Sergio Dias, from the band Os Mutantes, whose controversial thoughts, music and behaviour resulted in prison and exile for its leaders.
