I've always said that if I was some sort of music/talent scout, I'd spend the majority of my day navigating the New York City Subway. Nearly everyone who "performs" is more talented than you'd expect, with the occasional person being primed for superstardom right then and there. This case is the latter.
A great medley--see what songs and personalities you pick up on--cedes to a bunch of NYC Subway in-jokes. Even if you've never traveled the subway however, it's essentially an ode the the great ridiculousness of public transportation.
Amazing job. Here's to this guy.
***Update. Apologies for wrong clip earlier. America is still the greatest country in the world.
