I saw this fella last night on the subway, and I tell you what, I didn't even want to catch my train. Tons of people swarmed around him, mesmerized by his one-man-band performance. When he broke a string, people took the opportunity to throw money in his little box. When a song was over, they paid him. When the trains arrived, they paid him. I have never seen a street/subway performer make nearly as much as he did in the ten or so minutes that I watched him play. The videos on his site don't do him much justice, although I do like this one.
