Music in the L

After locking my keys inside my car in downtown Chicago - I didn't even have a chance to put the paid parking slip back in the car; we were late for Clay Enos talk at the apple store, so I took the risk of getting a parking ticket. I left just as he was finishing up his talk, took the train back to my house. On the way I stumbled upon a couple of musician. They were better live. I shot this with my D90 and a sigma wide angle lens (not a great lens to focus with while shooting video). I got back, no ticket. It was a beautiful night out for a walk...

Here's a video and some stills:
