In 2013, soul singer Sharon Jones was diagnosed with cancer and underwent a major operation and chemotherapy. Well, that didn’t slow her down much at all, as this documentary from director Barbara Kopple shows.

When Jones got sick, she just shaved her head and kept on performing. The film shows her appearances on stage, in church services, on shows like Ellen and Jimmy Fallon, and her energy never dissipates. In the stretch between her diagnosis and now, she performed, released a Grammy nominated album (Give the People What They Want), and, unfortunately, her cancer returned (She informed people at the premiere of the film in Toronto in 2015 that she was starting another round of chemo that Wednesday). The film offers a convincing argument that a good, positive, strong attitude qualifies as one of the better weapons against disease. While the film is mostly about her personal struggles, the moments showing her performing will certainly inspire soul lovers to dig deeper into her catalogue and seek out filmed performances. She’s definitely one of a kind.
