Airs, Friday, June 1 at 8 p.m. When Janis Joplin knew what she wanted, there was little that could stop her. With her music, she pushed and experimented until it felt just right. Her fourth and final album – Pearl – showed Janis at the top of her game, working hard with a new band and new ways to use her voice. This one-hour radio special explores Janis’ final years and the making of Pearl from her sister and author Laura Joplin, road manager John Byrne Cooke, Pearl producer, the late Paul Rothchild, and author Holly George Warren.
