Last year, the Institute of Contemporary Art/Boston invited Brazilian artist duo Os Gemeos to hold their first solo museum exhibition in the United States, where the pair showed paintings and mixed media pieces. In conjunction with the eponymous exhibition, the brothers took to the streets to paint a large mural – one of the first of its scale in Boston – as a gift to the city.
