He's Jan Dutler. I met him while he was playing in the Jean Talon market (Yes, while buying your fruits and vegetables you can also find incredible people and music). When I arrived, it was only him and his harmonica, trombone, percussion & ukelele; and two or three persons around. I started to take some pictures, I was shy (I never know if the person wants to be photographed or not). In the middle of one of his songs he said, while improvising, "I would love to have those pictures". At this point, the shyness went away and I started shooting as a professional photographer (that I'm not and don't know how to be) to focus, zoom and try to  find the perfect spot to capture the moment. I may have stayed for about half an hour, maybe a little bit more. I thanked him because of the music (because I was seriously missing it), and for the moment, those that you don't expect but that make you smile. We talked for a while in spanish because he had traveled around Bolivia and he told me he came to Montréal to study theater and improvisation. I remembered those days in which I had an incredible improviser team and that now is around the world. An ordinary day in which everything changes. When I left, a whole public was clapping, singing, whistling and smiling with him.
