Art 180’s mission is to give youth a chance to express themselves through art. And this week it all comes out at “The Big Show,” which will highlight the 11 community-based programs in creative expression offered by Art 180 this spring. Exhibitions of visual art projects will be on display, while performance-based art forms will unfold onstage throughout the evening. Projects include sculpture from members of the William Byrd Community House, multimedia art from students at Elkhardt and Henderson middle schools and paintings from children at Oak Grove Elementary School. The Big Show takes place at Plant Zero Art Center on Wednesday, May 15, from 6-8 p.m. Free. art180.org.
