It's a New Year, and we're not out of the winter concert doldrums yet. But anyone who tries to suggest that there's nothing going on in this town ought to get slapped. It's easy to forget, so let's give you a gentle reminder: One of the founding fathers of rock & roll plays at Blueberry Hill's Duck Room once a month. It's one of the coolest things on earth. If you've never seen Chuck Berry play, then get thee to the Duck Room on Wednesday, January 19. And if you have seen him before -- well, you haven't seen him this year. Get on it.
