That may be true but this “experiment” doesn’t show it. For one thing, if he was busking in NYC he would earn an order of magnitude more money. Because NYC has more people who are attuned to music and use the subway. For another, you’re failing about a performance in a subway. The acoustics aren’t great at all. Finally, a classical performance isn’t ideal to attract subway listeners. You have a couple of seconds to draw their attention because most of them are on their way to catch a train, catch a connection, or reach their destination. So all this says is that the best musicians cannot draw the attention of people by a few seconds of performance.
