For the price of a few beers the other night, I lent my camera to a friend who is photographing the North American International Auto Show today, so naturally I didn't expect I would be taking any worthwhile photographs on my Monday back at work. But walking past the State Theatre in downtown Ann Arbor, I came across this delightful musical duo. I ran back to my office, grabbed a dusty old Nikon D2H, and headed back to the scene. I am not familiar with the setup of this particular camera, so I didn't get anything stellar. But for purely documentary purposes, here's what I witnessed amid today's 20-degree chill for $2 thrown into a hat.
