On the surface, it’s a normal, sold-out show on a Friday night just north of downtown Cleveland. The fans stretch around the corner from the front door; ticket holders excited for the They Might Be Giants concert they’re about to see, and those without tickets hoping to catch a break when they get to the box office. But this is not a normal show, and this is not a normal audience. These are the geeks. The nerds. Die hard rock fans of a different shade of crazy, waiting for their musical heroes to serenade them with catchy pop songs tinged with dark humor and insightful counter-culture references.
