Mural Arts Philadelphia’s citywide Monument Lab kicks off at the center of the city with a Saturday Spotlight event at City Hall, with music and food from 1–4 p.m. Look for a special appearance from Mural Arts’ friend, Tariq “Black Thought” Trotter of The Roots, and hear from artists working on Monument Lab projects in the City Hall area. Mel Chin’s project involves the ordinary citizen and representation, while Michelle Angela Ortiz’s Seguimos Caminando (We Keep Walking) spotlights immigrant families in collaboration with the Shut Down Berks Coalition. Hank Willis Thomas is at work on a sculpture that serves as a monument to community, strength, perseverance, and resistance to racial oppression. FREE.
