Roadside Attractions is turning up the volume for Mark Landsman's music docu "
Thunder Soul," scooping up North American rights to the Snoot Entertainment-produced pic.
"
Thunder Soul" tells the story of how alumni from Houston's storied Kashmere High School Stage Band gather together after 35 years to play a tribute concert for "Prof," their 92-year-old bank leader who broke the color barrier by transforming the school's mediocre jazz band into a funk powerhouse in the 1970s.
