In general terms, street performing isn't strictly a musical thing. There's all sorts of entertainment happening on the street. From a musical perspective, it's been proven that even the best players can be and do get ignored, even when flawlessly performing what is considered some of the most beautiful music in the world. It's a bit of both talent and the artistry of being entertaining. However, even the most talented entertainer can find himself befuddled on the street. I've seen well known musical celebs, completely fail at bringing their talents, that were born in a studio setting, to the acoustic scene on the street. Like anything, it's finding the right market for your skills and talents.
