If you haven't stopped by Nucleus on Alberta Street lately, now's a good time to visit the unassuming gallery—dual solo shows by multidisciplinary artist Nate Harris and creative sign painter Josh Stover lend a contemporary feel to the space. Harris' works are funky tesselations and often come housed in chic frames. Stover, the co-owner of the Richmond, VA-based Variety Shop studio, creates abstracted still lifes with a vintage, highly graphic aesthetic. by Lindsay Costello
