Megan Kamerick talks with filmmaker Carol Bash about her new documentary "Mary Lou Williams: The Lady Who Swings the Band."
Mary Lou Williams was one of the great innovators in jazz. She was a pianist and composer who shaped this music and mentored many of its greatest artists. And like jazz, she improvised, adapting with each passing decade. But there are still many people who don't know anything about her. Filmmaker Carol Bash traces the arc of her life and music in the documentary, which will air on KNME Channel 5 on Friday June 26 at 10 p.m.
