Artistic performances pop up unexpectedly in NYC. Sometimes they can be really in your face, like when a Mariachi band suddenly steps into your crowded subway car or when an 8-year old break dancer with a boom box starts doing backflips in the aisle.
Other musicians are more low-key and their sounds really help to enhance an ordinary experience, like commuting, by creating a lovely mood that asks for your attention without demanding it. Brother Han lives in that camp. I first heard him a few months ago in the High Street subway station and I was delighted to find him more recently performing right smack in the middle of the Brooklyn Bridge, perhaps the bestest New York stage of all.
