Expo: Tropicalia Exhibition, London

Tropicália was a 1967 installation by Oiticica, a 1968 album featuring Gilberto Gil and Caetano Veloso, a movement, a state of mind, an idea, a dream. Tropicália, wrote Torquato Neto, “is whatever is necessary”. Oiticica defined it as: “The cry of Brazil to the world.” Go check out the show at the Barbican for inspiration.\
