To most people, an old abandoned building is nothing more than a dangerous eyesore in need of a wrecking ball. But in the Capital District, hundreds of vacant structures will be transformed into works of art. Funded with a $1 million grant from Bloomberg Philanthropies, Breathing Lights will illuminate buildings in Albany, Schenectady and Troy beginning next year. The project is the brainchild of University at Albany art professor Adam Frelin, and architect Barbara Nelson. WAMC’s Brian Shield spoke with both.
