Commemorate the 150th anniversary of the Civil War by delving into 18 songs and ballads from the Civil War era. These are tunes that marched soldiers to war, comforted them in longing, united them with families, or helped say a last goodbye. Contemplate the solitude of Logan English’s version of “Pretty Saro,” or remember classics such as “Just Before the Battle, Mother” and “Down by the Riverside.” Though more than a century old, these songs continue to be relevant through ongoing reinterpretation.
