When Caetano Veloso performed his Trópicalia anthem "Alegria Alegria" (Joy Joy) at Brazil's TV Record musical festival in 1967, he was booed. Much of the audience was intensely nationalistic. They revered "authentically" Brazilian music and detested what symbolized U.S. colonialism. To them, "Alegria Alegria" was Americanized because it was a rock song and Veloso was backed by a rock group, Os Beat Boys. Many also didn't respond to its strange, fragmented imagery.

Walking against the wind
Without handkerchief, without documents
In the almost December sun, I go
The sun scatters into spaceships, guerrillas . . .
Teeth, legs, flags, the bomb and Brigitte Bardot
