A little over a year ago, Mac Premo found himself with a problem. He needed to move his studio from Boerum Hill, where he had spent the last several years, to a new but smaller location at the Invisible Dog Art Center in Cobble Hill, Brooklyn. As an artist whose stock-in-trade was working with found materials, Mac had accumulated a fair amount of cultural debris, as it were. The move meant that a purge would be necessary. “This is sort of indicative of my problem as a human, or my greatest attribute as a human, I’m not sure which,” says Premo. “My solution was to make an art project.”
