This weekâ??s Art Break takes groups as its theme. Group shows are a great way to learn about a culture, an art movement, a topic, or a new way to bring art to people. Our downtown pick this week is the full experience in one place: a brilliant display of Australian modern art created by Aboriginal artists. Visit this and our other picks for free â?? youâ??ll have a great time and come away with a new understanding of the power of art.
