How a new mural in Dorchester demonstrates the power of site-specific artwork

A mural that aims to celebrate "Unsung Heroes" was unveiled this week across the street from Freedom House in Dorchester. We talk with the artist, Karmimadeebora McMillan, about why she chose Freedom House, and the power of site-specific artwork. We're also joined by Charla Jones, board member of Now + There, an organization focused on curating public art.
