Sometimes described as Brazil's Bob Dylan (though their voices are chalk and cheese), Caetano Veloso is a singer-songwriter, activist and a founder member of the Tropicalismo movement that rocked the Dictatorship in the 1960s. This 2008 documentary catches him touring the US and Japan with his album A Foreign Sound. It's a relaxed affair, with the artist musing on language, being away from home, fame and fortune. Pedro Almodovar, David Byrne, and supermodel Gisele Bundchen weigh in.
