It's was Afros and pleated shirts, James Brown and Bootsy Collins. It was the '70s, and at an inner-city Houston high school history would be made. Charismatic band leader, Conrad "Prof" Johnson, would turn the school's mediocre jazz band into a legendary 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.
