Justin Dillon became aware of human trafficking in 2004, and has been fighting to make others aware of it and inspire change from the ground up. He released the "rockumentary" Call + Response last year. The film features performances by several musicians, including Matisyahu, and interviews with advocates like Gary Haugen, the president of International Justice Mission, interspersed with footage of people trapped in slave situations.

We spoke to Dillon about the power of music and how all of us can fight modern-day slavery.

“When I look back at my personal ‘graduating class’ from the orphanage, there were 16 of us,” recalls Alex Krutov, a graduate of the Russian orphanage system. “When I look at those 16 almost 15 years later, there are only four or five not involved in drugs, prostitution, in prison and four were dead before they reached 23. These are people I have known for 20-plus years, and it’s almost as if they don’t exist.”
