This Saturday UCLA Live is presenting “An Evening with Chris Ware and Ira Glass: Visible and Invisible Drawings,” a combination to make the heart of any self-respecting literary comic and culture geek beat heavy. The premise is something about giving the two of them the same topic as the basis of a story and having them present their stories together on stage without knowing what the other one did. But frankly, it doesn’t matter what the premise is. This one-time-only opportunity to see these two on the same stage is one of the reasons that you live in L.A. and not Omaha. If there’s any way you can make it, go. And hold up a lighter for me, ’cause I’ll be out of town and I’d trade an organ to see it.
