Early Saturday morning, members of BANGdance warmed up for the debut of “City Life” at the FAB! Festival. “We’re calling this, terrible as it is, full-on homeless,” choreographer Nathalie Matychak reminded her seven dancers, four of whom were sprawled out across folding chairs. Ms. Matychak, who has lived in the East Village since 2007, was inspired to create what she said was an “honest portrayal” of day-to-day life in the city, complete with a subway ride, a traffic jam, and a death that is largely ignored by the dancers. Hear and see more from her and from her performers in our audio slideshow.
