"Wura-Natasha Ogunji: Your Heart is Clean." New work by Austin-based artist and performer Wura-Natasha Ogunji ruminates on the ever-changing landscapes of the megacity of Lagos, Nigeria, where she has done much of her work, including compelling performances that investigate the complex roles in Lagos’ public spaces. For a new exhibit, Ogunji presents an installation of large-scale drawings of maps with video projections. Those are joined with small stitched works that combine graphite, ink and thread and videos created with a cell phone. Opening: 7 to 10 p.m. Friday. Gallery hours: 5 to 8 p.m. Fridays, noon to 5 p.m. Saturdays and Sundays. Exhibit continues through May 31. Mass Gallery, 501 Calles St. Free. www.massgallery.org

Saturday

"Sewn on the Street." The slow food movement promotes local sourcing of food and fair labor practices as a counteraction to the fast food industry. But could Austin start a slow clothes effort? That’s what textile artists Monika Jakubiak of Warsaw, Poland, and Rebecca Layton of Austin consider with their pop-up sweatshop that invites participants to sit down at a sewing machine and make clothes on the spot. Jakubiak and Layton will host an informal conversation with the participants about the true cost of what you’re wearing and who really pays for garments in our global economy. The event is part of the Fusebox Festival. Noon Saturday. Umlauf Sculpture Garden & Museum, 605 Robert E. Lee Road. Free. Overflow parking in the softball field lot opposite the museum. www.fuseboxfestival.com.
