(Brad Davis/The Register-Herald) Charleston resident Kim Shrader takes a break from setting up camp to play with Gonzo, her 3-year-old pitt bull/lab mix companion, during the opening hours of the Cluster Music & Arts Festival going on this weekend at Ace Adventure Resort Thursday afternoon in Minden. Shrader, a co-owner of Hole in the Wall Studios which specializes in blacklight art, came with a large group of fellow Charlestonians to the 2nd annual event, which was held in Flatwoods last year. Running through Sunday afternoon, it's a smaller event than the annual Mountain Music Festival but comes with a similar crowd and vibe.
