In a city that is all sensory overload — teeming sidewalks, roaring trains, tricked out cruisers blaring reggaeton — it becomes practically a matter of survival to be selective about what we choose to see and hear. We put on iPods. We bury our nose in a book. We simply block it out.

But the artists of Elastic City — a Brooklyn-based outfit that leads experiential walks in search of art and imagery — wants you to do just the opposite. They want to get you to listen (closely) to the drone of air-conditioning units and the calls of street vendors. And to help debut their newest walk of Brighton Beach, they have extended a special invite to eight WNYC listeners.
