About as good as jug band bass and ukulele can be. Seriously, they were really getting into it. When I do this, I always drop a few bucks in the box. They earn it as far as I'm concerned.
Cities would be less alive if these guys weren't out performing for us.
I always drop some coin whenever I shoot street entertainers. I don't feel anything with your images ... they lack an intimacy I seek. Get closer. Capture the sounds with your lens.
