Kathy Amos of Gainesville has always been drawn to the Atlanta Symphony Orchestra because the music it has produced “does something for my soul.” “Without the opportunity of not being able to see symphony, experience it live, watch the musicians, then I and a whole lot of other people are going to be the much poorer for it,” said Amos, executive director of Brenau University’s Center for Lifetime Study. And so, she and others are closely watching contract talks between the symphony and the Musicians’ Union.
