Atlanta Symphony Orchestra in Piedmont Park, Atlanta, 1995
I think this is from the Dogwood Festival in Piedmont Park, Atlanta in 1995. The Atlanta Symphony Orchestra was on strike, claiming that its funding body was skimping on the endowment. It was a mess. IIRC, the symphony president, Allison Vulgamore, managed to smooth things out and grow the endowment.
This gig was a player-led performance, a bit of grass-roots goodwill building. The black-clad fellow conducting in that one photo is Harry Blazer, founder of Harry's Farmers Market. I was told by a symphony member that he is a big supporter of the ASO.
