What is the name of this artwork?

I saw a painting/drawing recently. I would like to know either the name or artist of it because I would like to buy it. I'll try to describe it the best I can. It is sort of a graffiti style drawing, it is a black guy playing either a piano or a keyboard, I believe he was wearing a green long sleeve jacket, the viewpoint was on an angle lower than the person....I know there isn't much detail, but that's all I can think of. It was inside a tattoo shop called Nautilus Tattoo in Berlin, CT (in case anyone is from around there).
