Lately I've been noticing more subway musicians wearing funny masks or even full costumes. On the surface, it seems like a ploy to make up for other shortcomings. But I've actually heard some pretty good music from these acts. The guys pictured above we're churning out a nice jazzy rendition of The Police's "Walking on the Moon" at the L train platform at Union Square. Perhaps it's not enough to just play well anymore. There has to be something unexpected to get New Yorkers to pay attention for a decent length of time.
