In the bohemian district of Almagro in Buenos Aires, the wistful notes of the tango classic “Vida Mía” drift out a window of a small cultural center. Inside, on a makeshift dance floor, couples move carefully, studying their steps as they dance in the arms of another. All the pairs are same-sex or nongender-identifying: from slickly dressed silver-haired pensioners to artistic university students clothed entirely in black. Some dance with friends, others with lovers. Each individual in a couple takes turns leading the dance as music floats over the scene, its lyrics telling a story about love and loneliness, breathing and embracing.
