Tiago Gualberto is an Afro-Brazilian visual artist and researcher at the Afro-Brazil Museum in São Paulo. He’s in town for a series of events organized by the Brazil Initiative at Brown’s Watson Institute. That includes the exhibit “A Clothesline to the Past: Rhode Island Takes on Brazil,” a collaborative effort which is up now at the RISCA Atrium Gallery (across the street from the State House). Gualberto will give a talk and brief art demonstration for the general public in the community room at South Providence Library.
