Rene Perez, right, and Jose Cabra, members of Puerto Rico's band "Calle 13," show their gloved hands covered with oil to photographers as they visit the Aguarico oil field in Ecuador's Amazon region, Friday, May 2, 2014. Perez and Cabra are in Ecuador to support the government's campaign against the multinational oil company Chevron Corp., which has been fighting litigation that began two decades ago for contamination caused by a Texaco-led consortium in Ecuador's Amazon rainforest between 1972 and 1990.
