Brazilian cellist Diego Carneiro brings his music to conflict zones

Cellist Diego Carneiro comes from Brazil's Amazon Delta, a place known more for mango trees and tropical birds than classical music. When he plays the cello, it seems to become part of him, like another limb or another pulse. His face and body animate with every note, and his hair sways as he plays. Reporter Caroline Feraday met with the musician as he prepared to set off on one of his tours of conflict zones.
