Chris Cornell is pleased to announce the release of his new song "The Keeper", lead track on the original motion picture soundtrack for forthcoming movie "Machine Gun Preacher".

Based on a true story, the movie is directed by Marc Forster (Finding Neverland, Monster's Ball) and stars Gerard Butler (300, The Phantom of the Opera) as Sam Childers, a former drug-dealing criminal who finds faith leading him on a path to East Africa. Shocked by the mayhem in Sudan, Childers becomes a crusader for hundreds of refugee children fleeing death and enslavement.

A portion of all sales of "The Keeper" go directly to Sam Childer's Angels of East Africa charity. The track is now available for sale on iTunes and the full moviesoundtrack album is released September 20. Machine Gun Preacher hits select US theatres on September 23.
