Monologist Josh Kornbluth takes pleasure in finding the emotional component of seemingly mundane, self-deprecating subjects. “The Mathematics of Change” is, on the surface, about his failure to become a math prodigy, but on a larger level is also about expectations and potential. The premise of “Citizen Josh” centers on Kornbluth trying to complete his college senior thesis decades late, but the show simultaneously addresses issues about participatory democracy. And while the original basis of “Love & Taxes” was Kornbluth’s tax woes and his girlfriend’s demand that he solve them before they got married, it’s ultimately about the importance of tax law, according to an interview Kornbluth did with Stanford’s McCoy Family Center for Ethics in Society earlier this year. Kornbluth — a so-called “red-diaper baby” (or child of communist parents) — has the ability to turn such dreary topics into hilarious commentary, but he’s always got an overarching (but not pedantic) ethical message tucked within. In other words, “Love & Taxes” should be the perfect New Year’s Eve show for reflecting on past shortcomings and gearing up for better times ahead — or, at the very least, preparing you for the upcoming tax deadline. Kornbluth will perform two shows of “Love & Taxes” — a feature-length film version of which is currently in production — at Rhythmix Cultural Works (2513 Blanding Ave., Alameda), capped off by a champagne toast at midnight.
