It’s called the Old Fiddlers’ Convention, but this documentary about the 2015 iteration of the world-renowned old-timey music event in Galax, Va., spends much of its time focusing on the kids. Plenty of performances are interspersed with interviews with fiddlers, guitar-pickers and maybe the stray mandolinist. It was at this convention that an 11-year-old guitarist named Presley Barker won the guitar competition — for adults. Proving it was no fluke, he repeated the victory two years later. Barker, who is now 14, will perform after the screening.
