Sigma Sound: The Sound Heard 'Round the World
In the 1960s, while America was in the throes of race riots, five people from diverse backgrounds came together in Philadelphia to create a new sound: Philly Soul. Its home, Sigma Sound Studio, was a place that drew Chubby Checker, The O'Jays, Stevie Wonder and many more. This film tells its amazing story.
