"Call & Response" is a feature documentary about the issue of human trafficking worldwide. Justin Dillon from the 90's band Dime Store Prophets, learned of the issue while touring Russia. He immediately began holding benefit concerts, which eventually led to this documentary. "Call & Response" features artists like Moby, Natasha Bedingfield, Cold War Kids, Matisyahu, Imogen Heap, Talib Kweli, Five For Fighting, Switchfoot, members of Nickel Creek and Tom Petty's Heartbreakers, Rocco Deluca. I have been unsuccessful in finding a soundtrack for sale online, but I'm sure it will be out there soon. Check out the website for more info on the film and how to get involved.
