Graffiti comes into the gallery for Gamut’s latest, “Writers, Rebels, & Rejects.” While the exhibition features legally sanctioned work, the artists’ content hasn’t lost its edge, as pieces include clashing colors, dripping paint, and angry creatures. Featured artists include Biafra Inc., Wundr, Boxy Mouse, Luis Fitch, and Eric Inkala, among many others. See original artworks and examples of commissioned public art. Curator Cassie Garner also had artists create works on miniature white box trucks, and a few artists have designed printed pieces to be pasted onto faux electrical boxes. The opening reception runs from 7 to 11 p.m. Saturday, September 15, and will include live painting from Rogue Citizen and music by DJ Sammy Figz. The closing party is from 7 to 11 p.m. Saturday, October 13. Free; $5 for opening and closing receptions.
