I guess it would be pretty cool to be riding the subway home from a show or an early night bar-hopping session and run into Arcade Fire playing in Union Square in New York City.

From let’s do this…[via brooklynvegan]

We’re walking up the stairs from the N,R at Union Square, bout 2a.m. Sat night. Couple street musicians are banging out some tune when we get up to the park.—-It’s Arcade Fire.

Covering New Order. Win and Will on guitars. Regine on guitar-case-as-percussion. Why the f*** not? It’s a nice night in New York, why not blow the dozen wanderers’ minds who’ve magically stumbled upon this scene?

Cover a couple more, then wrap it up with Tunnels.

I love the idea of a guerilla gig. In fact, that’d be a cool name for a band: Guerilla Gig. Hell yeah.

Update: brooklynvegan has the link for some video, too.
