Off the tops of our heads, we can't think of too many classical/chamber pieces written in honor of our fair city. This one, 1973's "San Francisco Polyphony," is by Hungarian-born composer György Ligeti who's most famous for scoring parts of Stanley Kubrick films like 2001 and Eyes Wide Shut. It's, like, dissonant and you can't exactly dance to it. But we welcome any imaginative suggestions for what all that scary ruckus is around 3:50 -- Embarcadero Station at rush hour?
