Dr. Kathy Bullock and Friends will perform the “Songs of Slavery and Emancipation,” a powerful collection of songs originally written and sung by abolitionists and enslaved people in hopes of freedom on Sunday, Sept. 18, at 3 p.m. in Berea College’s Phelps Stokes Chapel. The performance is part of the Stephenson Concert Series. Dr. Bullock, the former chairperson of the College’s Music Department, is one of three music directors on the project.
