Civil War operas are proliferating. A few I missed:
Freedom and Fire!
Cold Mountain
The Dream of a Good Death: A Civil War Folk-Rock Opera
Rappahannock County
My Civil War
What's interesting here is the idea, among producers, that the Civil War history crowd might be as arcane and fringe-y as American opera goers.
Or maybe they think that ACW readers will buy tickets to anything ACW-ish.
