Claude Schmitz’s new thriller, “The Other Laurens,” is cloistered in tone and adamant about it. Nothing is right in this threnody about the bonds of family. Forget the story that unfolds in a little under two hours: Take into account the overriding air of exhaustion and muffled sense of balance. Thomas Turine’s soundtrack iterates as much, beginning, as it does, with a flourish worthy of a spookhouse organ. Mr. Turine’s subsequent contributions don’t backtrack on this kitschy inflection.
