Chelpa Ferro is an art group formed in 1995 by the Brazilian artists Barrão, Luiz Zerbini and Sergio Mekler. Barrão made a name for himself in the 1980s, by using banal materials, from refrigerator components, to television parts and other fragments of household appliances, to create sculptures with a sense of humour. Luiz Zerbini is one of the most recognized Brazilian painters and Sergio Mekler is one of the most sought after editors of video and cinema in Brazil. Chelpa Ferro is an old colloquial Portuguese term for money, chosen by the artists because of its sound. The group use every day objects to create sculptures, installations and music performances which explore the dynamics of sound.
