HUNDER SOUL tells the true story of Conrad O. Johnson and the legendary Kashmere Stage Band. It was afros, pleated pants and platform shoes; James Brown, Sly Stone and Bootsy Collins. It was the ’70s, and an inner-city Houston high school was about to make history. Charismatic band leader, Conrad “Prof” Johnson would turn the school’s mediocre jazz band into a legendary, world-class funk powerhouse. Now, 35 years later, his students prepare to pay tribute to the man who changed their lives, the 92-year-old Prof. Some haven’t played their horns in decades, still they dust off their instruments determined to retake the stage to show Prof and the world that they’ve still got it.
