The 6Music presenter embarks on a quest to understand Latin Music's enduring appeal. Arriving in Rio, Huey learns that Brazil's newly elected government has come out against the hedonistic atmosphere of carnival and that Mangueira Samba School group is just one of many planning a protest. Later, he meets Gilberto Gil, who pioneered a new, politically conscious sound known as Tropicália. It was so radical - and its social implications so profound - that Gil was imprisoned and finally exiled in 1969. In Salvador, Huey meets percussionist Carlinhos Brown to talk about how afro positive music has shaped the sound of Brazil.
