On Christmas Eve of 1914, you didn’t hear gun shots or explosions. Instead, the sound of song broke out between the trenches on the Western Front. Now the Charleston Concert Association will recreate that evening with All is Calm: The Christmas Truce of 1914, a choral and spoken-word performance that commemorates this moment in history through a musical arrangement of European carols, war songs, and a cappella voices. The playwright Peter Rothstein’s main purpose is to “put a human face on war” through the use of actual quotes and letters collected from 30 World War I soldiers. Erick Lichte and Timothy C. Takach composed the musical arrangements for the men’s vocal ensemble Cantus. The concert includes some pretty emotional and moving scenes, like when a brave German soldier stepped into No Man’s Land and began singing “Silent Night.” German soldiers joined Allied soldiers in No Man’s Land to share food, drinks, and Christmas songs. They played games of soccer and buried each other’s dead. Obviously, the truce didn’t last, but we’re reminded that even in times of war the human capacity to empathize is not lost. Sometimes it takes more courage to put a gun down than it does to pick one up.
