The Canadian singer-songwriter Lights grew up in a missionary family in Timmins, Ont., believing that her musical ability was both a gift and a responsibility. Some of her earliest work was Christian music. When Lights was just a teenager, she started posting her songs on Myspace, which ultimately set her career into motion. But during that time, she also started questioning her faith. Lights joins Tom Power to talk about the healing she did to sever her ties with religion, plus, her new album, “A6,” which was inspired by the sights and sounds of Berlin.
