The Love + Radio host and creator Nick van der Kolk has a knack for finding subject matter that’s widely appealing, emotionally compelling, and, well, weird. This season, he’s continued to diversify the topics, voices, and soundscapes featured on the show: “The Episode about Animals” features lighthearted animal factoids and trippy sound engineering, while “Gotcha!” is the surprising story of a radio DJ whose crank call opens his colleague up to love and grief. There are also headier episodes such as “Cathedrals Have a Body Count,” in which a lawyer and performance artist discusses her work representing sex offenders. Love + Radio creates space on all sides of difficult issues, pushing listeners to consider even the ideas that make them uncomfortable, and this season might be its most provocative yet.
