Pedro Reyes is a Mexican artist who has taken 6,700 seized and decommissioned guns donated by the Mexican government and turned them into ... musical instruments. (Wouldn't have been my first guess.) The result is a haunting version of John Lennon's "Imagine" like nothing I've ever heard before. A man is playing a flute made from a gun. Need I say more?
As Reyes says, he is "turning these agents of death into instruments of life." I'm not a religious person, but amen.
