Writes a friend:

Lew,

A month ago some New York City “hardcore” bands performed in Tompkins Square Park for an estimated 2,000 to 3,000 people.  A packed together crowd, little masks, some in the crowd bouncing up against each other, etc.  A “narrative” would be that only stereotypical “rednecks” and such would participate in such an event at the time, but this shows otherwise, and also apparently looks like a relatively safe event weeks later.   Alas, it hasn’t got much coverage, but perhaps your readers would find it interesting, irregardless of their musical tastes.
