The L.A./Islam Arts Initiative is already under way at dozens of venues across the city, from the gorgeous Doris Duke’s Shangri-La and accompanying contemporary Islamic art group show at Barnsdall, to foodie events, workshops, screenings and concerts — with programming continuing through December. Its goal is not only to educate new audiences about the rich eclecticism and high-stakes urgency of understanding historic and contemporary Islamic arts but also to articulate and strengthen the shared bonds and common goals of an international coterie of artist-led resistances to oppression and injustice. Among the most salient of its offerings is this weekend’s pop-up exhibition and workshop in Chinatown, as Medina hosts Histories Absolved: Revolutionary Cuban Poster Art and the Muslim International — a survey show of political graphics linking the struggles of Cuban and Muslim cultural revolutionaries — along with a hands-on workshop by the Self-Help Graphics Barrio Mobile Arts Studio, an organization that knows a little something about fomenting cultural justice through art itself. As with the entire initiative, the Medina event hopes not only to educate but also to inspire creativity and engagement on your own terms. Medina, 977 1/2 Chung King Road, Chinatown; Sat., Nov. 8, 6-10 p.m.; free. laislamarts.org.
